Seattle Seahawks All-Pro cornerback Richard Sherman saw his 2017 season come to an abrupt end after nine games due to a torn Achilles tendon.

However, the recovery process may have taken a minor step back as head coach Pete Carroll has revealed that Sherman is expected to undergoing another surgery to “clean some stuff up,” according to Gregg Bell of The News Tribune.

“He's going beautifully. He's got another surgery coming up, his other leg, to clean some stuff up,” Carroll said in his end-of-the-season press conference at Seahawks headquarters, two days after 2017 ended with a home loss to Arizona and Seattle out of the playoffs for the first time since 2011.

“Not the same Achilles surgery that he had but he will have to a much lesser-degree recovery. It will be a four-to-six week thing, he thinks. But he's going to take care of himself to make sure that he's right. That's really important. He's really on the positive side. He's had a tremendous attitude about it. He feels pretty darn good. I think he's out of the boot (for his Achilles) like this week or something like that. So on goes his progress.

“I think in the next couple weeks he'll do the other one. He's got a cleanup job that he needs to do. He had a problem on both sides throughout the year.”

There doesn't appear to be too much concern about the second surgery on the injured area in the last couple of months. This had marked the first major injury of Sherman's career through his first seven years in the league.

Although Carroll is quite confident with the recovery process, the 30-year-old is dealing with a major injury that could have a huge impact on his performance on the field. He has established himself as one of the premier defensive backs in the league.

Sherman figures to still factor into the team's long-term plans despite many questions around the future of the franchise on that side of the ball. All this figures to lead to an intriguing offseason where there could be plenty of movement on the roster.
