The team learned that forward Dana Tyrell will require surgery to repair an ACL in his right knee. The ligament in need of reconstruction is the same one he injured in 2009.The incident occurred during the Bolts' home game on Jan. 15 against the Pittsburgh Penguins when his foot became tangled with an opposing player, causing his knee to twist.Tyrell did attempt to play through the injury, but it was determined that the knee was not stable enough to continue any further. He is expected to be out for the season.In 26 games this season, Tyrell recorded five assists and logged an average of 10:30 in ice time."I strongly believe that any team that does well has a lot of good foot soldiers, and he's definitely one of those guys," head coach Guy Boucher said. "People will label players as a hitter, a fighter, a scorer or a passer. There's one type of individual we never label and they are puck retrievers. They're probably the most important guys in the game."That's what (Tyrell) does best. If he's not able to play, it's less pucks for the team, for sure."
