Shane O'Brien

With his NHL opportunities exhausted, O'Brien remained a free agent over the summer and into the 2016–17 season. On January 10, 2017, O'Brien opted to sign his first contract abroad, agreeing to an initial two-week contract that would extend for the remainder of the season with Finnish club, HPK of the Liiga.

Midway into the following 2017–18 season, O'Brien was signed to strengthen the blueline of Austrian club, EHC Black Wings Linz of the EBEL, on November 9, 2017.

On July 16, 2015, O'Brien signed as a free agent to a one-year, two-way contract in a return his original NHL club, the Anaheim Ducks. Unable to make the Ducks roster out of training camp, O'Brien added a veteran presence to AHL affiliate, the San Diego Gulls, for the duration of the 2015–16 season, posting 1 goal and 17 points in 57 games.

As a free agent O'Brien failed to attract significant interest and, on September 2, 2014, he accepted a professional try-out contract to the Florida Panthers training camp. On October 6, 2014, O'Brien was successful in earning a one-year, two-way contract with the Panthers.

On June 27, 2013, O'Brien was traded by the Avalanche along with David Jones to the Calgary Flames in exchange for Alex Tanguay and Cory Sarich. On January 25, 2014, O'Brien was placed on waivers by the Flames. Unclaimed, O'Brien was assigned to affiliate, the Abbotsford Heat, marking a return to the AHL for the first time since 2006. On June 30, 2014, O'Brien was placed on unconditional waivers for purposes of a compliance buyout.

With the option of impending free agency again looming, O'Brien was re-signed by Colorado for $6 million over three years on June 26, 2012. Affected by the lockout-shortened 2012–13 season, O'Brien was unable to emulate his previous year as he was relegated primarily as a depth defenseman to register only 4 assists in 28 games.

On July 13, 2011, he was signed to a one-year contract with the Colorado Avalanche. Acquired to initially to provide depth insurance to the defense, O'Brien impressed out of training camp and made his Avalanche debut on the opening night of the 2011–12 season in a 3-0 defeat to the Detroit Red Wings. With his experience, physicality and leadership he quickly became a fixture on the defense of a youthful Avalanche team and appeared in his 400th career game in a 4-1 loss to the San Jose Sharks on November 20. With a more prominent role entrusted than given with former clubs, O'Brien matched a career high with 17 assists and finished with 20 points for his best statistical season since 2008. He also finished second amongst the Avalanche with 105 penalty minutes.

Later in the season, on March 30, 2010, head coach Alain Vigneault announced that O'Brien would sit out the next three games for disciplinary reasons. According to the Team 1040, a local sports radio station, O'Brien showed up late for the previous Monday's practice. Besides the incident, however, Vigneault added there was more to the situation than O'Brien being late. O'Brien was not permitted to skate with the team until April 4. He finished his second season in Vancouver with two goals and eight points over 65 games. In the 2010 playoffs, he added a goal and two assists in 12 games as the Canucks were eliminated by the Blackhawks in the second round. Following the Canucks' playoff elimination, he discussed his upcoming restricted free agency and commented on a desire to have more leeway with the coaches. On October 2, 2010 the Vancouver Canucks placed O'Brien on waivers.

Three days after being placed on waivers, O'Brien was traded to the Nashville Predators, along with Dan Gendur, for Ryan Parent and Jonas Andersson. While in Nashville he tied a career high in games played (80) adding two goals and seven assists during the 2010–11 season. He played in the all of the Predators 12 playoff games but went unsigned by Nashville following the playoffs and became a free agent.

In the subsequent 2009 playoffs, O'Brien scored his first goal as a Canuck against the Chicago Blackhawks in game six of the second round. The goal tied the score at 3–3 in the second period, although Chicago went on to eliminate the Canucks 7–5.

Becoming a restricted free agent in the off-season, O'Brien re-signed with the Canucks to a one-year, $1.6 million contract after turning down the arbitration process. Following an altercation with the New York Rangers on November 3, 2009, O'Brien was suspended for one game by the NHL for poking Rangers forward Sean Avery from across the two teams' benches with his stick. On December 20, 2009, O'Brien scored his first goal in 102 regular-season games in a 3–1 loss to the St. Louis Blues.

After finishing his rookie season with a combined total of two goals and 16 points in the regular season between Anaheim and Tampa Bay, he was re-signed by the Lightning in the off-season. At $2 million over two years, the contract saw O'Brien make $875,000 the first year and $1.125 million in 2008–09 – a raise from his $495,000 salary of the previous season. He would improve to four goals and 21 points in the subsequent season.

On October 6, 2008, O'Brien was traded with forward Michel Ouellet to the Vancouver Canucks for defenceman Lukáš Krajíček and prospect Juraj Šimek. During his first year in Vancouver, O'Brien received a minor fine of $2,500 on January 29, 2009, after taking part in a post-game altercation with Ryane Clowe and Joe Pavelski of the San Jose Sharks nine days earlier on January 20. Pavelski allegedly speared Canucks forward Daniel Sedin at the end of the game, a 2–1 overtime loss, leading O'Brien and teammate Willie Mitchell to intervene.

At the trade deadline on February 24, 2007, O'Brien was dealt with a third-round draft pick in 2007 to the Tampa Bay Lightning for goaltender Gerald Coleman and a first-round draft pick in 2007. He had established himself as a fighter during his rookie season. At the time of his trade, he was ranked fifth in the league in fights with 12. Making the transition to Tampa Bay, however, his role as an enforcer was diminished as the club was less prone to fight than the Ducks had been. He made his NHL playoff debut with the Lightning on April 12, meeting the New Jersey Devils in the first round.

Playing major junior in the Ontario Hockey League (OHL), O'Brien was drafted by the Mighty Ducks of Anaheim in the 8th round, 250th overall, in the 2003 NHL Entry Draft. Before earning a full-time roster spot with Anaheim, he played with their minor league affiliates, the Cincinnati Mighty Ducks and Portland Pirates of the American Hockey League (AHL). O'Brien led all AHL defenceman in scoring during the 2006 Calder Cup playoffs with six goals and 22 points in 19 post-season games. The Pirates had made it to the semi-finals where they were defeated in seven games by the Hershey Bears. In the off-season, he was re-signed by the Ducks to a one-year contract on August 3, 2006.

O'Brien made his NHL debut against the Los Angeles Kings on October 6, 2006. He scored his first NHL goal later that month against Dominik Hašek in a 4–1 win over the Detroit Red Wings on October 18. He completed the night with a Gordie Howe hat trick by getting an assist and a fight against Brad Norton. On November 8, he scored a goal and two assists against the Vancouver Canucks for a three-point night.
