Bruins captain Patrice Bergeron said he's uncertain about his NHL future after Boston's crushing Game 7 overtime loss to the Florida Panthers on Sunday night.

Bergeron, 37, is an unrestricted free agent this summer. Bruins players had talked openly about sending off Bergeron and fellow veteran center David Krejci, also 37, with a Stanley Cup win. Bergeron is in his 19th season. Krejci, who is also a free agent, has played 16 seasons.
