Bruins forward Daniel Paille suffered a head injury during Boston's 2-0 loss to the Panthers Thursday night at TD Garden. Florida's Krys Barch collided with Paille early in the first period and the Bruins' forward did not return. After the hit, he lay on the ice for a few moments and was tended to by team trainer Scott Waugh. Paille skated off on his own but did not return.
