Seahawks running back Chris Carson has a broken bone high up in his left leg as well as likely a high ankle sprain, coach Pete Carroll said during his weekly radio show on ESPN 710 Seattle.

Carson was injured when tackled by Indianapolis’ Jon Bostic after a run for no gain with 6:37 left in the game.

While Carroll said Carson had a “significant” ankle injury after the game some reports proved confusing with some players indicating it was not serious.

Carroll clarified Monday morning why there was some confusion and that the injury is “way more” significant than he had said after the game.

“Last night when they did the initial X-rays his ankle was fine,” Carroll said. “He’s got a fracture that’s way up just below his knee. It’s not a displaced one and all that but because of the torque of the way it happened it was not in the area they were focused on so I told the team he didn’t have a broken leg and everybody was excited about that for him. But he does. … it was not in his ankle it was in his upper leg. We don’t know that means yet.”

Carroll said Carson has not yet had an MRI to determine the full extent but that “unfortunately, yeah, he’s going to be out.”

Carroll said Carson also “likely has a legit high ankle sprain, which is as bad as a break sometimes if it’s a really bad one. We don’t know that yet either so we’ll find out.”

Carson had his leg placed in an air cast and was carted off the field with teammates flooding onto the field to console him.

Carroll also said defensive end Cliff Avril briefly lost feeling in his hands when he suffered a neck injury in the first quarter. Avril was injured when trying to chase down Indianapolis quarterback Jacoby Brissett with 5:20 left in the first quarter.

“He had something happen, got kicked in the chin by the guy’s heel when he was tackling Brissett,” Carroll said. “He got something happened, spinal injury, that caused him a little bit of loss of control for a second in his hands. He came back fine and felt OK but something happened there so we are going to be really careful there to make sure we know exactly what is going on and take our time. It will take us a while to figure this out.”

Carroll also said it remains unclear exactly what the issues are with offensive lineman Rees Odhiambo, who had the wind knocked out of him on a play in the third quarter. Odhiambo remained in the game and played all 68 snaps. But he then had difficulty breathing in the locker room after the game and after being stabilized was taken to a hospital for observation. Carroll said Odhiambo, the team’s starting left tackle, remained in the hospital as of 9:30 a.m. Monday.

“He had a response, he got hit in the chest on the interception return (by the Colts’ Malik Hooker in the third quarter) and it wasn’t a violent hit but the guy must have caught him just right with the shoulder and it knocked the wind out of him,” Carroll said. “That’s what happened on the field and he had trouble really breathing through the game but he made it — it was OK. But in the locker room it just exacerbated so we took all the precautions and made sure we looked after him.”

Carroll said he didn’t have specifics of what his injuries may be though the NFL Network reported that it may be a cardiac contusion.

Carroll also said cornerback Jeremy Lane suffered a “strained” groin on the first series.

In some good injury news, Carroll said running back C.J. Prosise, who sat out the game with an ankle injury, had a good pregame workout and that he “would be shocked if he doesn’t make it back this week. … surprised he could run as hard in pregame.” Carroll said based on that that Prosise should “be able to get back” for next Sunday’s game against the Rams.

That will help in a backfield that will be without Carson for an extended time.

The rookie had become Seattle’s starting tailback and if he is gone for a significant time — and maybe even the season — then the Seahawks will have to turn back to the veteran duo of Eddie Lacy and Thomas Rawls to take over, as well as J.D. McKissic, who saw his first action of the season on Sunday and scored a 30-yard touchdown.

Lacy served as Carson’s backup and ended with a team-high 52 yards on 11 carries — 43 coming on Seattle’s final possession after Carson was injured.

“He looked good,” Carroll said of Lacy, signed by Seattle as a free agent last March after four years in Green Bay. “I thought he looked exactly like we hoped. He looked big and strong and tough and very decisive and he just needs to get some more carries to get going.”

Lacy had not had a carry since the opener against Green Bay when he had just three yards on five carries.

Rawls was somewhat surprisingly a healthy inactive for the game.

But Carroll said afterward he’ll be needed now.

“With Chris banged up we’re so fortunate to have Thomas ready to jump back out there,” Carroll said. “We’re just lucky that we have a guy like that who’s ready to go and is healthy and all that.”
