Richard Sherman out for the season after suffering torn Achilles vs. Cardinals

The Seahawks just lost a key member of their secondary

The Seahawks picked up a big divisional win against the Cardinals on Thursday, but the victory came at a steep price. 

Following Seattle's 22-16 win, Seahawks coach Pete Carroll announced that Richard Sherman would miss the rest of the season after tearing his Achilles against the Cardinals. 

"The doctors are really clear about it, he ruptured his Achilles," Carroll said, via the Seahawks. "There's no coming back from that until you get surgery."

The Seahawks' All-Pro corner went down in the third quarter after getting tangled up with John Brown following an 18-yard catch by the Cardinals receiver.

Going into the game, Sherman had been listed on the Seahawks' injury report with an Achilles ailment, and after Seattle's win, he said he felt pretty confident that his Achilles was going to pop at some point this season. 

"I knew what was happening," Sherman said, via the Seahawks. "It's been bothering me all season. It was one of them things where you just have to play through it as long as you can and when it goes, it goes."

Despite the injury, Sherman's most vivid memory from the play was the fact that he didn't make the tackle. 

"I thought I could get the ball and once it popped, it was just unfortunate I couldn't make the tackle," Sherman said. "It's unfortunate, it sucks. If it was anything I could play with, I would be out there." 

As he walked off the field, Sherman seemed to know that he was likely done for the season. After being examined by team doctors, the Seahawks corner walked up and down the Seattle sideline giving out hugs to his teammates.

The injury to Sherman is a devastating loss for a Seahawks team that's already dealing with one big injury in the secondary. Earl Thomas missed his second straight game on Thursday and hasn't played at all since injuring his hamstring in Seattle's 41-38 win over Houston in Week 8. 

The absence of Sherman means that the Seahawks are going to have to play without him for the first time in his career. Since being drafted back in 2011, Sherman hasn't missed a single game, a streak that includes 105 regular season games and 12 playoff games. 

The fact that Sherman got injured during a Thursday night game won't be lost on the Seahawks, as most of their players have been adamantly against the mid-week night game. After the win over Arizona, Doug Baldwin said that Thursday night games "should be illegal."

Sherman also wrote an essay in December 2016 where he referred to Thursday games as a "poopfest."

"Poopfest. It's terrible," Sherman said. "We got home like 1 o'clock in the morning, something like that on Monday [before their 2016 Thursday game] and then you've got to play again. Congratulations, NFL, you did it again. But they've been doing it all season, so I guess we're the last ones to get the middle finger."

Sherman wasn't the only Seahawks player who left the game on Thursday. Newly acquired left tackle Duane Brown (ankle)  and defensive tackle Jarran Reed (hamstring) both had to leave the game in the first half. C.J. Prosise was also injured. The Seahawks running back was immediately ruled out after hurting his ankle in the third quarter.
