Bruins coach Claude Julien said Satan suffered the cut just before a brief altercation with Tampa Bay's Steve Downie, who had thrown a big hit at Satan after the winger circled the Lightning net and passed the puck to the front. After the brief one-sided altercation ended, Satan was seen looking at his right hand.
"He cut his hand from a skate," Julien said. "We're going to see what the prognosis is. We've got a day before the next game. So this is a situation where I might be able to give you more [Friday]."
The Bruins play the Florida Panthers on Saturday in their last game before the Olympic break.
