The Capitals defenseman took his last shift in the second period.

WASHINGTON — The Washington Capitals are down to five defensemen in their season opener, as Matt Roy has left Saturday's tilt with the New Jersey Devils with a lower-body injury.

Roy will not return to Saturday's contest. The severity of the injury is unclear at this time.

It's unclear what happened to the 29-year-old blueliner, who was making his Capitals debut. His last shift came roughly three and a half minutes into the second period, though nothing appeared to be ailing him.

Roy skated 8:39 minutes in his Capitals debut and was a minus-2.
