Percy Harvin avoids IR with workout

A throwing session Percy Harvin had with quarterback Russell Wilson on Monday, which went extremely well, helped persuade Seattle Seahawks coach Pete Carroll not to place the wide receiver on season-ending injured reserve, league sources said.

Sources said Harvin, who has played in just one game this season following offseason hip surgery, looked "amazing" during the session and that the Seahawks believe it is possible he will play when the team opens the postseason at home Jan. 11.

The plan for now is to have Harvin rejoin practice Thursday.

One Seahawks player told ESPN that Harvin seemed more optimistic than he had been in quite a while.

"I think he physically feels good, which affects his attitude," the player said.

Harvin declared that it was "go time once again" through his Twitter account Monday night, and followed that up with a tweet in which he vowed to prove his doubters wrong.

Harvin, who signed a $67 million, six-year contract with the Seahawks in March, had surgery Aug. 1 to repair a torn labrum. He hasn't played since Week 11 because of soreness and inflammation in his hip.

Carroll had been pessimistic about Harvin's status during his radio show Monday morning, but by the afternoon, after watching Harvin catch passes from Wilson, he had changed his stance.

"It will be a great thing for him [if he plays]," Carroll said. "This guy is a true competitor. To his credit, he has not given up on it. He's at a place where he has a chance. We'll see what happens."
