The Seahawks lost Saturday's preseason game, falling 30-3 to the Denver Broncos, and unfortunately they also saw two players, linebacker Ben Burr-Kirven and receiver John Ursua, go down with what head coach Pete Carroll described as serious knee injuries.

"Johnny U and BBK, both of those guys got hurt seriously tonight, and it breaks our heart," Carroll said. "This is a rough game and sometimes it takes a toll, and those two kids are hurt. We'll see what happens with them, but it's going to be a while."

Burr-Kirven was carted of the field after the game's opening kickoff, an injury that was all the more unfortunate because the kick went deep into the end zone for a touchback. In the second quarter, Ursua went down while running a route.

"You just hate to see it anytime, especially on a play that's a touchback like that in the preseason," said fullback/linebacker Nick Bellore, Seattle's special teams captain. "It's rough to see, and someone that's a cornerstone of the special teams and a great linebacker in his own right. It's awful to see something like that. I hope he's OK, I haven't really heard, but it's never good when someone gets carted off like that."

Also leaving the game with an injury was safety Ryan Neal, who has an oblique injury.

"He has an oblique strain," Carroll said. "Sometimes those are kind of gnarly. We'll see if he can get through it, I don't know. That can take a little while sometimes, it just depends on how he responds, but it's in the rib cage."
