Fourth-line center Mathieu Perreault was sent to a Buffalo area hospital for evaluation after the Capitals’ 4-2 loss to the Sabres and did not return to Washington Monday night with the team.

Perreault, who was speared by his own stick late in the third period at First Niagara Center, is expected to rejoin the team on Tuesday according to a team spokesman.

With 5 minutes and 59 seconds remaining in regulation of Washington’s 4-2 loss to the Sabres, Perreault collided with defenseman Christian Ehrhoff in the corner of the offensive zone. It appeared as though Perreault’s stick got pushed into his midsection on the play.

The 23-year-old Quebec native went down in a heap on the ice where he was attended to by head athletic trainer Greg Smith. Perreault ultimately skated off under his own power and took three more shifts, including one where he was whistled for a charging penalty, before the conclusion of the contest.

“I think he lost his wind,” Coach Dale Hunter said. “He went into the boards and [his] stick hit him in the tummy.”

The team said afterward that Perreault “sustained an upperbody injury and was sent to the hospital for precautionary reasons.” In 23 games this season, Perreault has three goals, seven points, a plus-1 rating and 12 penalty minutes.
