Capitals defenseman Mike Green could face supplementary discipline for a hit he delivered on Tampa Bay rookie Brett Connolly in the middle of the second period of Thursday night’s game.

Dmitry Orlov was riding Connolly into the boards behind the Washington net when Green skated in and drove the upper portion of his left arm and shoulder into the Lightning winger’s head 11 minutes 6 seconds into the period.

Connolly dropped to the ice in a heap unable to stand but eventually skated off under his own power and would return to the game in the third period and play another 3:44. If you haven’t seen the hit yet, check out the video below and resume reading.

After the game, Green was not made available to comment but a team spokesman said the defenseman would speak to reporters on Friday.

Tampa Bay Coach Guy Boucher believes the league will look at the hit.

“I saw it. The league has to look at that. It’s right at the head. The head’s targeted. For me, it’s clear,” Boucher said. “The ref didn’t see it. But, you know, the refs are on the ice. They can’t see everything. It happens so fast. There’s people beside them.

“To me, it could have been a five [minute major penalty],” Boucher added. “It’s a head target. It’s clear. We just watched it on video.”

No penalty was called on the play but given that Connolly’s head was the principle point of contact and the winger was already in a vulnerable position – both points of emphasis in previous suspensions this year -- it is possible that Green could face a disciplinary hearing with Brendan Shanahan, the NHL’s vice president of player safety.

Connolly simply said “I’m not going to point any fingers. It’s a hockey play it happens.”

Green has received supplementary discipline once before in his career. In January 2010, Green received a three-game suspension for elbowing then-Florida forward Michal Frolik in the head.
