Following his team's 4-3 loss to the New York Rangers in Game 4 of their Eastern Conference Quarterfinals series, Washington Capitals coach Adam Oates revealed that wing Martin Erat was dealing with an upper-body injury and would be reevaluated on Thursday prior to Game 5 on Friday in Washington.

Erat left the game with 1:34 remaining in the opening period and appeared to be favoring his arm following a hard collision involving Rangers center Derek Stepan and Caps winger Alex Ovechkin.

With Stepan rushing towards the net, both Ovechkin and Erat initiated contact on Stepan. Ovechkin and Erat were both assessed two-minute minors on the play, with Jason Chimera serving Erat's hooking minor.

Erat lost his left glove in the collision and appeared to slam his left arm hard onto the ice before sliding into the Capitals' net, where he laid in obvious discomfort for several moments. The Czech veteran, who was acquired at the NHL Trade Deadline from the Nashville Predators, was evaluated following the collision and did not return.
