C.J. Prosise, J'Marcus Webb in spotlight when Seahawks host Cowboys

RENTON, Wash. -- The Seattle Seahawks take on the Dallas Cowboys in their third preseason game Thursday night. Here's a position-by-position look at what to keep an eye on.

Quarterback: Russell Wilson and the first-team offense have not produced any points so far. Their first six drives have resulted in four punts, an interception and a turnover on downs. Is that reason to panic? Of course not. Still, the coaches would like to see the offense find some rhythm, especially considering that the starters figure to play into the third quarter.

Running back: Third-round pick C.J. Prosise is the player to watch here. He suffered a hamstring injury on the first day of training camp but will see preseason action for the first time this summer.

"He’ll play throughout, kind of just sprinkled in plays, just to see what he can do," Seahawks coach Pete Carroll said. "This is the first step; it’s a big deal."

The Seahawks drafted Prosise hoping he could be their third-down back right away, but he needs to perform and stay healthy the next couple of weeks to earn that role.

Wide receiver: It's been a strange competition here, with no one really stepping up to claim the fifth spot. Doug Baldwin, Jermaine Kearse, Tyler Lockett and Paul Richardson are all in place. Can the likes of Kenny Lawler or Antwan Goodley stand out and earn a place on the roster?

Tight end: Sleeper name to watch here: Tanner McEvoy. The undrafted free agent began his career with the Seahawks at safety. He then moved to wide receiver and now has been getting reps at tight end. Jimmy Graham's status for the Sept. 11 regular-season opener is in jeopardy, and Nick Vannett has a high ankle sprain. That leaves the Seahawks with Luke Willson and Brandon Williams. Versatility is a big factor with the final roster spots. McEvoy will get a chance to show he's got additional value.

Offensive line: Carroll made an interesting comment about the offensive line Wednesday.

"We’re pretty settled right now," he said. "However, we’re just allowing the competition to play itself out, and we don’t want to cut off anybody’s opportunities. It’s more likely not to change a lot, but we want to keep the competition open, and the guys are showing that they’re worthy of that."

The starters, from left to right, have been: Bradley Sowell, Mark Glowinski, Justin Britt, Germain Ifedi and Garry Gilliam. The interior seems set, but J'Marcus Webb will get a chance to steal a tackle spot. The Seahawks signed him thinking Webb would play right tackle, but he's been dealing with a knee injury. This will be his first preseason action.

Defensive line: Second-round pick Jarran Reed (toe) won't play. Frank Clark was very active in the first two preseason games and will continue to line up all over the defensive line. Young players such defensive tackle Quinton Jefferson and fullback Brandin Bryant will look to flash.

Linebacker: It seemed like the coaches wanted Eric Pinkins to emerge and win the Sam linebacker job, but that hasn't happened. Mike Morgan is the veteran and the safe pick, but Cassius Marsh still has a chance to make some noise.

Cornerback: Not much movement here during the summer. One thing to consider: It's unlikely that Tharold Simon, Tye Smith and Marcus Burley all make the roster. Would the Seahawks possibly consider trading one of those players before teams cut down to 53?

Safety: Kam Chancellor (groin) is healthy and ready to play. The two players to watch continue to be Brandon Browner and Tyvis Powell.
