After spending his first seven NHL seasons with the Senators, he played for the Atlanta Thrashers, Pittsburgh Penguins, Detroit Red Wings, and Chicago Blackhawks.The Winterhawks went on to clinch the championship in overtime and Hossa returned to the ice on a chair as his teammates pushed him around with the Memorial Cup to celebrate the victory.Despite missing two months, Hossa managed 15 goals and 15 assists for 30 points in 60 games to earn NHL All-Rookie honours and finish second to the Colorado Avalanche's Chris Drury in Calder Memorial Trophy voting for rookie of the year.However, late in the season, on 11 March 2000, he was responsible for an on-ice accident in which he high-sticked Toronto Maple Leafs defenceman Bryan Berard on the follow-through of an attempted shot.[5] Hossa recorded 32 goals and 75 points in 2000–01, finishing second in team scoring behind Alexei Yashin[6] and earning his first NHL All-Star Game appearance in Denver.Unable to come to terms before training camp for the 2001–02 season, Hossa sat out the first two weeks before signing a three-year, $8.5 million contract on 26 September 2001.Hossa would regain form in 2002–03 with a career-high 45 goals, 35 assists and a team-leading 80 points,[8] while competing in the 2003 NHL All-Star Game in Sunrise, Florida.He then led the Senators to a long playoff run where they were ultimately eliminated in seven games by the eventual Stanley Cup-champion New Jersey Devils in the Eastern Conference Finals.Beginning the season in Slovakia, he joined Mora IK of the Swedish Elitserien to play with his younger brother Marcel after 19 games with former club Dukla Trenčín.[12] In his Penguins debut two days later, Hossa injured his medial collateral ligament (MCL) in a knee-on-knee collision with Glen Murray of the Boston Bruins.[13] Hossa missed the next six contests before rejoining the team for the conclusion of the regular season, playing on a line with Dupuis and captain Sidney Crosby.Complementing an already high-powered offence led by Evgeni Malkin and Crosby, Hossa proved to be a vital cog in the Penguins' run to the 2008 Stanley Cup Finals.[16] He finished third in playoff scoring with 26 points, behind Conn Smythe Trophy-winner Henrik Zetterberg of the Red Wings and linemate Sidney Crosby.After missing two games due to a neck injury late in the season, Hossa was taken off the ice in a stretcher after falling head first into the boards following a check from St. Louis Blues defenceman Roman Polák on 3 March 2009.Escaping serious injury after having laid motionless on the ice for several minutes, it was revealed that in addition to minor neck complications, Hossa also suffered a bruised knee and was listed as day-to-day.The prospect of Hossa losing to the team he left in order to secure a Stanley Cup championship received considerable media attention.[30] The signing of Hossa by the Blackhawks coincided with the departure of the team's leading scorer and MVP from the previous season and former Ottawa Senators teammate, Martin Havlát, to the Minnesota Wild that same day.[36] During the Blackhawks' first playoff series in 2010, Hossa received a five-minute major penalty for boarding Nashville Predators defenceman Dan Hamhuis.In the ensuing overtime, Hossa scored the game-winning goal on Predators goaltender Pekka Rinne seconds after exiting the penalty box.[39] Hossa was the first player in NHL history to go to the Finals in three consecutive seasons with three different teams, a feat that would subsequently be repeated by Corey Perry in 2020, 2021 and 2022.[41] In the first period of Game 3 of the opening round of the 2012 Western Conference Quarterfinals, he was taken off the ice on a stretcher and briefly hospitalized after being hit by the Phoenix Coyotes's Raffi Torres.[44] Hossa then scored seven goals and nine assists for 16 points in 22 games in the 2013 playoffs as the Blackhawks eventually defeated the Boston Bruins to win the Stanley Cup in the Finals.[45] On 30 October 2014, shortly into the 2014–15 season, Hossa scored his 1,000th career point with a goal against the Ottawa Senators, becoming the 80th player in NHL history to reach the milestone.Both of the Hossas have played together for Mora IK of the Elitserien during the 2004–05 NHL lockout and on the Slovak national team in the World Championships and Winter Olympics.Coincidentally, they were both dealt by their NHL teams on the day of the 2007–08 trade deadline — Marián from Atlanta to Pittsburgh and Marcel from the New York Rangers to the Phoenix Coyotes.
