Per Stephen Whyno:
Here's the hit:
Washington Capitals defenseman Jack Hillen left Saturday night's season opener against the Tampa Bay Lightning after taking a hit into the boards from Vinny Lecavalier.
Hillen's left shoulder hit into the boards after Lecavalier struck him with what appeared to be a clean check. He was down on the ice and in pain until the whistle blew with 8:17 left in the second period.
Hillen was attended to on the ice but skated off under his own power, favoring his left arm. He went down the tunnel to the team's locker room.
