ARLINGTON, Texas—The Seahawks came out of Friday night's game relatively clean from an injury standpoint, but did have a couple of players leave the game with injuries. 

Defensive end Alton Robinson "banged his knee on the ground, fell on it," Seahawks coach Pete Carroll said, and will have further tests done to determine the severity of the injury. Robinson was able to walk off the field under his own power after being tended to by athletic trainers. 

Carroll said second-year guard/tackle Jake Curhan has an elbow injury, the severity of which is not yet known.

Carroll said the two weeks between now and the opener should give Seattle time to get some injured players back: "We'll see a number of guys be able come back the next couple of weeks, we'll see a number of guys get back out there, so we'll see how it works."

One player the Seahawks are hoping to get back is rookie running back Kenneth Walker III, who had a procedure last week following what Carroll described as a hernia issue, though not a sports hernia.

Carroll said Walker will, "have a chance to make it for the opener."

Another player the Seahawks are hoping to get back soon is cornerback Sidney Jones IV, who has been out with a concussion.

"Sidney's just clearing the concussion stuff," Carroll said. "Let's cross our fingers that he can. He feels OK 99 percent of the time, but he still got a little something there that he can report, so we're just being really careful with it. Two weeks from now he should be ready to go."
