Alexei Cherepanov

The investigation into Cherepanov's death continued for several months. In December, reports out of Russia indicated that blood and urine samples collected from Cherepanov showed that he had been engaged in blood doping. This was later clarified, as Russian officials said that what initially appeared to be blood doping was actually an attempt by team officials and doctors to treat Cherepanov's condition surreptitiously. After this revelation in January 2009, the KHL suspended five Avangard officials and doctors for attempting to treat a condition which should have only been managed by experienced cardiologists. The investigation into Cherepanov's death was reopened in August 2009, after federal prosecutors ruled that the previously suspended team physicians were unaware of his heart condition, and had not prescribed the medications he was taking. Cherepanov's agent, Jay Grossman stated that tests conducted by the NHL prior to the 2007 Entry Draft had not shown any health problems.

Shortly after Cherepanov's death, Avangard Omsk retired his #7 jersey in a ceremony prior to a game against Dynamo Minsk, with his parents in the crowd. The KHL renamed its Rookie of the Year award the "Alexei Cherepanov Award" starting in 2009. An Under-20 tournament, held in August 2013, was dedicated to his memory. The tournament featured 6 teams including two Russian clubs, and national sides from Great Britain, Poland, Belarus and host Lithuania.

After his death, the New York Rangers sought compensation in the form of an extra draft pick from the NHL. As Cherepanov had not agreed to terms with the club at the time of his death, the team claimed that he was technically eligible to be selected in the 2009 NHL Entry Draft, and they were entitled to compensation. The team was eventually awarded the 17th selection of the second round in the 2009 draft, after the Rangers' proposal was approved by the rest of the league. NHL general managers also voted to adopt a rule change, dubbed the "Cherepanov rule" that would see any future teams receive compensation if a prospect selected in the first round dies before signing a contract.

During a KHL game in October 2008, Cherepanov collapsed on the bench near the end of the game, and could not be resuscitated. He was pronounced dead later that day in hospital at age 19. His cause of death was attributed to heart failure, although there were varying reports as to the specific nature of his underlying medical condition. After his death, the KHL launched an investigation into the emergency response provided by the home team during the game, and also into team officials and physicians for their treatment and management of Cherepanov's health during his career. Avangard retired Cherepanov's #7 jersey after his death, and the KHL renamed its Rookie of the Year trophy to the Alexei Cherepanov Trophy.

Cherepanov's final international appearance for Russia came at the 2008 World Junior Championships, where he helped Russia to a bronze medal. He was particularly effective in the third place game, recording 3 points during a 4–2 victory over the United States. He finished the event with six total points (three goals and three assists).

Cherepanov died on 13 October 2008 after collapsing during the third period of a KHL game against Vityaz Chekhov. After finishing a shift, Cherepanov skated to the bench with his teammates, Jaromír Jágr and Pavel Rosa, where according to coach Wayne Fleming, "He just laid back, passed out and went kind of white." Jagr immediately shouted for assistance. Attempts were made to revive Cherepanov at the bench, and when they were unsuccessful he was carried back to the team's dressing room by his teammates, where doctors continued to work. Cherepanov was transferred to a local hospital but he was pronounced dead later that evening. Initial reports claimed that he had died of a heart attack.

Cherepanov was eligible for the 2007 National Hockey League (NHL) Entry Draft after the 2006–07 season. Throughout most of the season leading up to the draft, Cherepanov was the top ranked prospect in Europe. Prior to the draft, Cherepanov attended the NHL's Scouting Combine, allowing club's to evaluate his physical attributes and schedule interviews, if they needed additional information prior to his selection. Those attending the combine were struck by Cherepanov's apparent physical immaturity, pointing out his low number of bench press repetitions, and his physique. His performance during the interview portion of the event was more impressive, with team personnel impressed with his maturity and good attitude. At the draft, Cherepanov was selected by the New York Rangers in the first round of the draft, 17th overall. Some attributed Cherepanov's lower draft selection to concerns about his availability for the NHL, considering the lack of a transfer agreement between the NHL and the International Ice Hockey Federation (IIHF) concerning Russian players. Analyst Pierre McGuire believed Cherepanov was a legitimate NHL prospect, stating, "He was built for the new-age NHL with his speed, his skill and his ability to make things happen offensively." Cherepanov was excited to be selected by the Rangers, saying, "I believe that New York is the center of the United States and I'm very happy to be selected by the New York Rangers."

Cherepanov attended the Rangers' prospect camp shortly after he was drafted in 2007. At the start of the 2007–08 season, Cherepanov returned to Avangard playing in 46 games and scoring 15 goals, this time in the newly created Kontinental Hockey League (KHL). Entering the 2008–09 KHL season, Cherepanov had one year remaining on his contract with Omsk. The Rangers had been attempting to have Cherepanov released from the contract since shortly after he was drafted. During the 2008–09 season, Cherepanov was joined on the Avangard roster by Czech forward Jaromír Jágr. Cherepanov played 14 games with Avangard in 2008. At the time of his death, he was second on the team in goals with seven, and fourth in points.

Cherepanov represented Russia at multiple age level tournaments during his junior hockey career. He made his international debut at under-20 level in 2007, at the tournament in Sweden. Cherepanov and the Russian team finished with the silver medal after losing to Canada in the gold medal game. Cherepanov was named the tournament's Best Forward and also secured a spot on the tournament All-Star Team. He scored five goals and added three assists to finish with eight points. He was also selected by his coaches as one of Russia's three best players for the tournament. Later that same year, Cherepanov stepped down to his age group and helped Russia win the gold medal at the 2007 IIHF World U18 Championships, scoring a goal in the final against the United States. Cherepanov was named Russia's Player of the Game for the gold medal game. Cherepanov earned a spot on the tournament All-Star Team, and was selected as one of Russia's top three players again.

The 2007 Super Series was a tournament that pitted the top junior hockey players in Canada and Russia against each other in an 8-game series to commemorate the 35th anniversary of the 1972 Summit Series. After being drafted by the New York Rangers earlier in the summer, Cherepanov was one of the biggest names on Russia's roster heading into the series. In the second game of the series, Cherepanov suffered a concussion after a hit from Brandon Sutter and was out for the remainder of the series.

Cherepanov was born in Siberia, and played minor hockey for the Motor Barnaul organization. The remote location of his youth hockey play made Cherepanov an unknown quantity until he left the region to join the Avangard Omsk organization. He made his debut for the team in the Russian third division during the 2005–06 season, appearing in five games and scoring two goals. During the 2006–07 season, Cherepanov split time between Avangard's club in the Russian Superleague (RSL) and the Russian third division. While playing with the top level club, Cherepanov scored 18 goals and added 11 assists in 46 games. His 18 goals set a RSL record for players his age, and exceeded the production of his Russian predecessors, Alexander Ovechkin and Evgeni Malkin, when they were at the same level. For his play the previous season, Cherepanov was named RSL Newcomer of the Year.
