Pittsburgh Penguins forward Blake Comeau left Monday's game against the Florida Panthers midway through the third period with an apparent injury.
Bryan Rust took Comeau's spot on the line with Evgeni Malkin and Nick Spaling.
There is a chance the injury is serious, head coach Mike Johnston told reporters after the game. It may be a wrist issue, according to Dave Molinari of the Pittsburgh Post-Gazette.
