Boston Bruins defenseman John-Michael Liles has a concussion and will be out indefinitely, the Bruins announced prior to their game at the Philadelphia Flyers on Tuesday.
Liles was injured during the first period of a 4-1 win against the Tampa Bay Lightning on Sunday when he tripped over Lightning goalie Ben Bishop's stick and fell awkwardly into the end boards.
