In the second quarter of Sunday's road game against the Cleveland Browns, Will Dissly suffered what Seattle head coach Pete Carroll would later call a "serious" injury to his Achilles. The setback came as the second-year tight end worked to get open for a throw from quarterback Russell Wilson while the Seahawks were in the red zone.

"He did hurt his Achilles. We don't have the final on it, but it's a serious one," Carroll said postgame. "He's got to get some tests and stuff like that, MRIs and all that, but it's a big loss."

Dissly, whose rookie year came to an end four games into last season due to a torn patellar tendon, had recorded a team-leading and career-high four touchdowns for the Seahawks heading into Sunday's game against the Browns.

"He's been playing great football," said Carroll. "If you saw him, he's running in open field and it just happened like Achilles do, they come out of nowhere. It's a devastating injury for him for this season. Will's done everything he can. He's been an unbelievable Seahawk. Every play that he's been in for us, last year and this year, he was just top-flight and a first-class competitor in all ways. It's just unfortunate that he's going to have to miss this deal here if the tests come through like we think they will."

Added quarterback Russell Wilson: "Yeah, that was tough today. That was tough on Will and tough on us, tough on me. I've developed such a great relationship with Will and I just want him to keep the faith. He's had a tremendous year. It's tough because it's back to back years, but I think that he's still young, if anybody's as tough as nails it's him. There's nobody tougher that I know. He'll come back stronger. We'll support him. We'll love him. It's just a tough part of the game, unfortunately, is just injuries and stuff. I think that more than anything else I just want him to stay encouraged, to keep the faith, and keep believing that great things are going to be in store for him. We'll make sure that we do everything we can to make sure that's the case."

Behind Dissly, the tight end position features Luke Willson, who recently rejoined the Seahawks, and Jacob Hollister, an offseason trade acquisition who was called up from the practice squad prior to Seattle's Week 6 game. Veteran Ed Dickson, meanwhile, is currently on the team's injured reserve list and could be eligible to return after eight games. And offensive lineman George Fant, who started at left tackle Sunday in place of an injured Duane Brown, has also seen snaps as a big tight end/sixth offensive lineman in Seattle's offense.
