Doan has Grade 3 shoulder separation

GLENDALE, Ariz. -- Phoenix Coyotes captain Shane Doan had a Grade 3 right shoulder separation, the team revealed after dropping the seventh and deciding game against the Detroit Red Wings in their first-round series Tuesday night.

"That injury is usually 3-4 weeks and he's trying to push it into 3-4 days," head coach Dave Tippett said after his team's 6-1 defeat. "I just felt so bad for him because he wants to play so bad. We even tried him in some battles [in practice] yesterday and it was obvious that he couldn't play at the level needed.

"It was bad enough where... it wasn't a good injury."

It was the fourth straight game the star winger missed after suffering an upper body injury in Game 3.

"I'd give anything to be out there and help my teammates, obviously [I] had been waiting a long time for a game like this," Doan said after the game.

Doan played all 82 regular-season games.

"We certainly missed him," said Tippett. "For us to get to the top of our game, it was hard to have him out."
