Chicago Blackhawks forward Marian Hossa is day-to-day after suffering an upper-body injury prior to Monday night's Stanley Cup final game against the Boston Bruins.
The Blackhawks said on their Twitter account that "something apparently happened during warmups."
But coach Joel Quenneville said after Game 3 that Hossa suffered the injury prior to the pre-game skate.
Hossa was tied for the team lead with 15 points in the playoffs. He was third in the regular season on the Blackhawks with 17 goals.
Ben Smith replaced Hossa in the lineup. Smith, who played at Boston College, appeared in one game for Chicago during the regular season.
