The rehabilitation period was estimated at six months, meaning he would will be able to compete again around Christmas, missing at least the first half of the 2018–19 2. Bundesliga season.

On 18 February 2017, in his fourth Bundesliga game with Hamburg, he was substituted in the first half due to a shoulder injury. On 1 March 2017, Papadopoulos returned in the DFB Cup against Borussia Mönchengladbach. On 18 March 2017, in a 0–0 away draw against Eintracht Frankfurt, he reached 100 appearances in the Bundesliga wearing the jersey of four different clubs.

On 21 June 2017, having narrowly avoided relegation the previous season, Hamburger SV signed Papadopoulos on a permanent three-year deal from Bayer Leverkusen on a €6.5 million transfer fee, with the Dinosaurs to offer another €3 million in the form of a target bonus, for the next three years. On 9 August 2017, despite having been with the club for only six months, he was named vice-captain for the 2017–18 season. On 12 December 2017, he scored his first goal for the season in a 2–1 home loss against Eintracht Frankfurt.

On 21 September 2016, he made his debut with the club as a substitute in a 1–1 Bundesliga match against Borussia Mönchengladbach. On 24 November 2016, Papadopoulos underwent a successful routine surgery to overcome a chronic knee problem. and started a rehabilitation program, with his return to action estimated at approximately three weeks.

On 8 March 2015, Papadopoulos scored his first Bundesliga goal for Bayer Leverkusen against SC Paderborn. His injury misery continued after, on 25 April 2015, he dislocated his right shoulder in a league match away against 1. FC Köln. Leverkusen officials reported that Papadopoulos would return to the training after three months.

On 7 June 2015, Bayer Leverkusen opted to make Papadopoulos' loan from Schalke 04 permanent on a €6.5 million transfer fee, with the player signing a five-year contract. On 29 September 2015, Papadopoulos scored his first goal in the 2015–16 season in the first half of a Champions League encounter against Barcelona: Hakan Çalhanoğlu, swung in a corner that hit right underneath Barça goalkeeper Marc-André ter Stegen's crossbar; Papadopoulos headed in the rebound from close range. Papadopoulos suffered a lot of injuries during the season facing a tear in a joint capsule that kept him two weeks out of training, as well as a right calf tendon in the 0–0 Europa League draw with Villarreal that kept him out of the club till the end of the season.

On 17 April 2015, Papadopoulos was recalled by new Greece manager Sergio Markarian, as part of a selection overhaul, to participate in the nation's European Championship qualifier away at Hungary.

On 3 August 2014, Bayer Leverkusen signed Papadopoulos on a season-long loan deal. He told Leverkusen's official website, "I am very happy that it worked out with the change. Bayer 04 is a club just like Schalke with major international ambitions. Unfortunately I was injured more often in the past season. But now I'm back fit and highly motivated to achieve with Leverkusen both my personal goals as well as the club's."

On 3 November 2014, Leverkusen announced that Papadopoulos had been ruled out for the remainder of 2014 with a shoulder injury. The centre-back suffered the injury in the final training session ahead of his side's UEFA Champions League away match with Zenit Saint Petersburg; he underwent surgery. "That's just bitter for Papa," Leverkusen coach Roger Schmidt told reporters ahead of Leverkusen's trip to Russia. Following his injury, the club announced that Papadopoulos underwent successful surgery on the following Monday in Herne.

After a very difficult year for the defender marred by injury (383 days to be exact), Papadopoulos returned to action in a home game against SC Freiburg in December 2013. Just a few weeks after his return to action, however, Papadopoulos suffered a new shoulder injury and could have been forced to undergo surgery. The news came as another blow, as his recurring knee problems restricted him to just four appearances in the 2013–14 season. The injury also forced him to miss the 2014 World Cup with Greece.

Ahead of the 2012–13 season, Italian club Milan were interested in signing Papadopoulos. After showing interest, Schalke accused Milan of making an illegal approach for Papadopoulos without the club knowing. Also interested were Russian giants Zenit Saint Petersburg, but when their £16 million bid for Papadopoulos was accepted by Schalke, Papadopoulos rejected the move, opting to stay in Germany. In September 2012, Papadopoulos signed a new contract with Schalke that will keep him at the club until 2016. On matchday two of the 2012–13 season, Papadopoulos scored his first goal of the season, and third in the Bundesliga, in a 3–1 win over FC Augsburg. A virus, however, would later kept him out of play for a number of games, and he would later undergo surgery in an attempt to correct a knee injury he suffered in a 3–1 loss away at Hamburger SV in November 2012.

Papadopoulos was a member of Greece's 23-man squad for the finals of UEFA Euro 2012, starting in the team's second and third group games, as well as the quarter-final loss to Germany.

Having finished an excellent year with Schalke, on 4 June 2011, then-Greece head coach Fernando Santos called Papadopoulos up for the first time to the senior squad for a match against Malta. Due to an Avraam Papadopoulos injury and Sokratis Papastathopoulos' inability to play, he took their place in the squad in the centre of defence next to Vangelis Moras. Not only did he have an excellent game, but he also scored the second goal of his team. On 6 September 2011, he scored his second international goal against Latvia in UEFA Euro 2012 qualification.

Having made his first league appearances for Olympiacos at the age of 15, Papadopoulos moved to Germany in 2010 to join Schalke 04 and scored on his senior debut for Greece the following year, aged 19. However, his career progress in the Bundesliga was hampered by a succession of injuries over several seasons.

On 23 June 2010, German club Schalke 04 announced that they had signed Papadopoulos on a four-year deal, keeping him until 2014. On 21 August 2010, Papadopoulos made his Bundesliga debut for the club in a 2–1 loss against Hamburger SV. On 25 August 2011, in the qualification round of the UEFA Europa League, he scored his first goal for Schalke in a 6–1 win over HJK Helsinki.

On 17 December, Papadopoulos scored his first goal in the Bundesliga in a 5–0 win over Werder Bremen and scored the next game on 21 January 2012 in a 3–1 win over VfB Stuttgart. Since joining Schalke from Olympiacos, Papadopoulos has played in over 70 matches in all competitions, scoring five goals and has ultimately gathered respect and praise from all over Europe due to his tenacious and skillful defending considering his young age.

In September 2008, Papadopoulos signed a new contract with Olympiacos, which included a £4.6 million release clause, over three years. On 2 November 2008, he made his first league appearance of the 2008–09 season for Olympiacos at home to Ergotelis in a 2–0 home win.

Born in Katerini, Papadopoulos was playing for hometown club Svoronos Katerinis in July 2007 when he was invited on trial to train with the RCD Espanyol youth team during pre-season, with a view to giving the player a role in the youth team. Papadopoulos, however, performed well enough for the club's management staff to fast-track him to the reserve team, offering him a contract immediately.

The 2007–08 season was promising for Papadopoulos. He made his competitive debut for Olympiacos in the Greek Superleague as a substitute during a 3–1 win over Atromitos on 2 December 2007, thus becoming the youngest player to ever play in the Greek league at the age of 15 years and 283 days. He also made the substitutes bench in the UEFA Champions League against Real Madrid and Lazio, and featured in several Greek Cup games. If Papadopoulos had featured in any Champions League games, he would have broken the record for the youngest player to ever compete in the competition by nearly two years.

Papadopoulos was called for the under-19 Greek national team to participate in the Elite round of the 2007 UEFA European Under-19 Football Championship. He participated in all three group games against Moldova, Netherlands and Russia, helping Greece finish top and qualify for the finals. Papadopoulos later featured at the heart of the Greek defence in the finals tournament and was partners with teammate Konstantinos Lambropoulos. He was instrumental in keeping a clean sheet against the Czech Republic, as well as strong performances against England and Italy. His performances attracted attention from scouts of elite teams such as Manchester United, Arsenal and Chelsea.
