Seahawks injury update: Cooper Helfet has sprained ankle

RENTON – Tight end Cooper Helfet scored the only touchdown of Seattle’s win over Arizona.

He also sustained the only injury of note for the Seahawks, who could use some good fortune in that department given the quick turnaround with a Thursday night game against San Francisco.

“He’s the one guy that came out banged up. He sprained his ankle,” coach Pete Carroll said Monday. “Coop handles stuff really well. We’ll see what that means. But right now he won’t be able to run around until the end of the week. We’ll see what happens.”

Helfet made two catches on Sunday, the first of which was a 20-yard touchdown in the third quarter. He was injured on his other reception, limping off the field after making a 7-yard grab on the second-to-last play of the game.

Said Helfet afterward: “I’m alright. A little banged up. Regular football game. Tweaked my ankle, but I’ll be alright.”

Left guard James Carpenter missed his third straight game, also because of an ankle injury. Carroll said Monday that the team “labored” over whether or not to let Carpenter play before deciding to make him inactive with an eye toward ensuring his availability for Thursday’s game.

“We were working him out and he was really politicking to get out there and play,” Carroll said. “But we just thought that if he did, with the short week coming up we probably wouldn’t get him to respond. He was that close.”

Carroll said cornerback Marcus Burley (hamstring) and defensive lineman Demarcus Dobbs (knee) both have a chance to return by Thursday after missing Sunday’s game.

Rookie linebacker Kevin Pierre-Louis, however, will not. Carroll’s comments hinted at the possibility that his season may come to an end due to a shoulder injury.

“He’s banged up pretty good,” Carroll said. “We’ll take a good look at him here. He won’t be able to make it for this week, and more news to come.”

Carroll was asked if Pierre-Louis might be heading to injured reserve.

“Don’t know yet,” he said. “Working on it.”
