Sharp, who collided with Phoenix's Rostislav Klesla, left the ice with the help of the training staff and went immediately to the dressing room.
The collision occurred with 1:35 left in the period. Sharp didn't return to the game and coach Joel Quenneville said he will be re-evaluated on Monday. Sharp was unavailable for comment.
Sharp has a career-high 68 points this season -- 34 goals and 34 assists.
