Here are some position battles to keep an eye on heading into Friday’s game at Minnesota

Who shines at receiver: Ben Obomanu, Courtney Taylor, Logan Payne and Jordan Kent have all made plays at times during training camp. But the first to make a play in preseason action will take the lead in this tight competition at receiver. Obomanu looked good in practice this past week, but Taylor’s explosiveness after the catch and Kent’s ability to stretch a defense also make them desirable picks to fill in until Deion Branch is ready. Payne probably will not play due to cracked ribs.

Another big game for Forsett? Rookie Justin Forsett was one of the bright spots in the Seahawks scrimmage last week, but will he respond again with a big performance? We’ll see. Forsett brings a different dimension to Seattle’s offense with his elusiveness, but more than likely he’s headed to the practice squad at the end of the preseason.

Look for Forsett and T.J. Duckett to get a lot of carries again, as Julius Jones and Maurice Morris will probably see limited action. Folks thinking Morris is vulnerable should squash those thoughts. Morris knows the offense the best out of any of the running backs, and is a favorite of Holmgren. Mo is not going anywhere.

Kicking game in the limelight: Punter Reggie Hodges has been kicking well of late. Now Seattle will see how he performs in game action. Ryan Plackemeier should be back next week, and is probably going to be the guy. But he’ll have to work for it the way Hodges is performing right now.

The contest at kicker also begins in earnest on Friday between veteran Olindo Mare and rookie Brandon Coutu. Both have been pretty consistent in camp, but one of them should step ahead in Friday’s game against the Vikings.

Pork Chop on the bubble? The reoccurring injuries may have started to catch up to Floyd “Pork Chop” Womack. Kyle Williams, an undrafted free agent signed by Seattle who spent his first season on the team’s practice squad, has looked OK so far during camp. Womack offers versatility with his ability to play guard and tackle. But Williams, unlike Womack, is healthy. It will also be interesting to see how centers Steve Vallos and Ben Claxton perform with starter Chris Spencer out.

Competition at D-line: A strong performance by rookie Lawrence Jackson could vault him into the conversation as a starter over Darryl Tapp. Jackson is believed to be stronger against the run than Tapp, and might make more sense as a starter on run downs. Jackson could then shift to defensive tackle and Tapp could come in and play defensive end during passing situations. And don’t forget about Baraka Atkins, who also has had a solid camp. Howard Green also will get a chance to shine with guys like Red Bryant and Larry Tripplett out with injuries.

Wallace-Adams debate: University of Washington product C.J. Wallace has played well so far in camp, but Michigan's Jamar Adams also has made an impact. Adams has a bigger frame than Wallace and is two inches taller. Wallace surprised some Seahawks’ observers by making the team last year as an undrafted free agent, and Adams is trying to do the same thing this season.
