RENTON, Wash. — Cornerback Josh Wilson ascended to a starting cornerback spot without much of an announcement.

He hasn’t been cleared to return to that position after suffering a concussion in the first half of last week’s game at Arizona.

Wilson, 24, missed all three days of practice this week and is listed as doubtful for Sunday’s game at Minnesota. If he is unable to play, Kelly Jennings will start in his place.

“We’ll see where he is Sunday,” coach Jim Mora said of Wilson, “but we’re kind of planning as if he won’t be there.”

Jennings is the auxiliary starter ahead of Ken Lucas, Mora said, based on how those players are currently performing.

Wilson stayed on the turf immediately after the injury, and Seattle’s trainers came out to tend to him. He recovered, jogged off the field on his own and returned to play.

“I think the adrenaline of the game kept him clear,” Mora said. “Then you get a chance to settle down, it settles in on you.”

Seahawks team policy is injured players are not to be interviewed about their condition or status so Wilson was unavailable for comment.

Cornerback Marcus Trufant also suffered a head injury in Sunday’s game at Arizona after he and linebacker Leroy Hill combined to tackle Arizona’s Tim Hightower on a fourth-and-1 inside the Seattle 10. Trufant stayed on his hands and knees after the play, but got up and made his way off the field before trainers were summoned.

Trufant did not practice Wednesday because of a concussion according to the team’s injury report.

“I was OK,” Trufant said. “I played the rest of the game, but afterward it was kind of a precautionary thing.”

Was it scary to think that he returned and played in the game after suffering that kind of injury?

“It doesn’t really scare me,” Trufant said. “That’s part of football. You play with dings and stuff like that. You run around, you’re flying around having fun, little stuff like that is bound to happen. You bounce back from it.”

Players are evaluated by the medical staff, which includes team physician Stan Herring — who is regarded as one of the nation’s foremost experts on diagnosing and treating concussions.

“They’re not going to clear a guy to play unless they feel like he’s capable of continuing and not further damaging himself, injuring himself,” Mora said.

Players are again evaluated in the days after the game before being cleared to practice.

Going for the throat

On Sunday, Cardinals defensive tackle Darnell Dockett told quarterback Matt Hasselbeck that it was an accident that Dockett’s forearm wound up crushing down on the quarterback’s throat.

On Friday, the league told Dockett it was a $7,500 accident. That’s the amount Docket was fined for roughing the passer. Television cameras showed Dockett pushing his arm into Hasselbeck’s throat. Dockett was not penalized on the play.

“I brought it up to him,” Hasselbeck said Thursday. “I said, ’Hey man, what was that all about?’ He apologized and said he didn’t realize he had done it. Stuff like that happens from time to time unfortunately.

“I’m going to try to stay out of piles, the bottom of piles. It’s a bad place to be.”
