Zacha (undisclosed) exited Tuesday's game versus the Canucks.
Zacha was hurt on his first shift of the game and needed some help to get to the locker room. The Devils didn't elaborate on the nature of his injury, and Amanda Stein of the Devils' official site reports he's doubtful to play Wednesday versus the Flames. If Zacha can't suit up, Mason Geertsen would likely enter the lineup.
