RENTON — Seattle Seahawks running back Marshawn Lynch’s back issue could be more of a concern than anticipated.
Lynch missed practice on Monday in order to receive treatment for back spasms that have been an ongoing issue for the Cal product since he arrived in Seattle.
Lynch played at Denver two weeks ago, but did not play last Friday against Kansas City.
Seahawks head coach Pete Carroll said Lynch will not play against Oakland on Thursday, as the training staff works to get him ready for Arizona in the season opener on Sept. 9.
“We’ll have rested him a couple of weeks to make sure that he’s okay,” Carroll said. “So we’re taking care of it with this one. He’s had back conditions in the past, so we’re just making sure we’re doing the right thing and taking all the time that is available.
Reserve quarterback Matt Flynn threw the ball and worked out for about half of the practice Monday, before shutting it down and icing his sore elbow. Carroll said he’s hopeful Flynn can get up to full speed today, and play against Oakland on Thursday. Third-string quarterback Josh Portis is expected to play against the Raiders as well.
The Seahawks announced the Tarvaris Jackson trade to Buffalo has been finalized. Seattle reportedly received a seventh-round pick that could be upgraded to a sixth-round pick in the 2013 draft depending on Jackson’s playing time.
The Seahawks also released cornerback Coye Francies to get down to 75 players.
Offensive lineman John Moffitt returned to practice on Monday and worked with the second unit. Carroll said if everything goes well, Moffitt will play on Thursday, but it looks like he’ll have to battle rookie J.R. Sweezy for his starting right guard job.
Safety Kam Chancellor, who had a sore hip that he rested against Kansas City, practiced Monday. … Players who did not practice include defensive end Jason Jones (knee), defensive tackle Greg Scruggs (hamstring), linebacker Matt McCoy (knee), receiver Doug Baldwin (hamstring) and safety Chris Maragos (shoulder). Cornerback Walter Thurmond (leg) and offensive lineman James Carpenter (knee) remain on the physically unable to perform (PUP) list.
