EDGE Analysis

The exact nature of the injury remains unclear, but the winger was unable to immediately return to the ice. The bottom-six forward tallied saw just 5:21 of ice time and recorded two shots on goal before leaving. If he's unable to rejoin the action, his next opportunity to play comes Saturday against the Sabres.
