The outlook doesn’t look good for Seattle Seahawks defensive end Cliff Avril.

Avril, who was kicked under the jaw by Colts quarterback Jacoby Brissett in Seattle’s Week 4 win over Indianapolis, has been seeking medical opinions on his neck injury and “serious stingers” suffered in the game.

It seems the Pro Bowl defensive end has finally found some clarity and will undergo neck disc surgery this week, according to Seahawks coach Pete Carroll.

“Cliff’s going to get surgery on Tuesday and get fixed up,” Carroll said on 710 ESPN Seattle’s “The Pete Carroll Show,” on Monday. “We’re really happy about that. He needs to get all fixed up.”

Carroll added: “It’s disc surgery-related. That’s all I can tell you. I’ve seen the pictures, but I can’t explain it.”

Avril was moved to injured reserve on Oct. 20 and eligible to be activated after Seattle’s game against the Jaguars on Dec. 10, but a return this season seems unlikely. Disc surgery has a recovery time of about six weeks, but can vary from patient to patient.

Carroll said he was uncertain whether Avril would suit up in a Seahawks uniform again.

“I think at this point that’s up to Cliff,” Carroll said. “He’s got to figure that out and we’ll let him answer that question.”

Avril, 31, is coming off a Pro Bowl season with 11.5 sacks in 2016. Multiple reports circulated that Avril’s injury was career-ending, but he has yet to confirm whether or not he wants to continue his playing career at this time.
