The Legion of Boom will be without one of its stars for the remainder of the season.
Coach Pete Carroll confirmed the injury after the game. "He's going to get checked and all that kind of stuff, but the doctors are really clear about it that he ruptured his Achilles. There's no coming back from that until you get the surgery and all that kind of stuff."
The star defensive back, who popped up on the Seahawks' injury report this week with an Achilles injury, was seen grasping his ankle immediately after colliding with Brown. He eventually got up and limped to the sideline.
"I kind of knew what the play was, I was going to make a break to catch a ball," said Sherman, who showed up to the postgame news conference on crutches and in a walking boot. "I was going to try to get me a pick. We were in a Cover Two and once I put everything on it, I knew -- I had gone pretty much the whole season not really making any drastic cuts. I'm veteran enough, I know the plays enough where I was never in position where I had to make a super bad cut or it probably would have popped a long time ago. I just thought I could get the ball and once it popped, it was just unfortunate I couldn't make the tackle."
"I knew what was happening," Sherman said. "I mean, it's been bothering me all season. So it was one them things you just have to play through as long as you can but when it goes, it goes."
The corner, who had two interceptions and 31 tackles heading into Thursday Night Football, was performing like he usually does, a big reason the Cards had just 130 passing yards heading into the fourth quarter. He was replaced by Jeremy Lane in the starting lineup.
