The Seattle Seahawks look every bit like the Super Bowl contender they were predicted to be this year, but they’ve now experience their first real setback this year. They’ll be without their All-Pro tackle, Russell Okung, for at least the next six weeks after he suffered a torn ligament in his toe in last week’s win over the San Francisco 49ers:

Seahawks officially placed Russell Okung on “IR-Designated for Return”. Also re-signed DT Michael Brooks to psquad, released WR Nick Edwards — Brian McIntyre (@brian_mcintyre) September 20, 2013

The IR-designated to return list allows a team to place a player on IR after the season has started, but bring him back after eight weeks. Okung can start practicing after six weeks.

With Okung out, starting left guard Paul McQuistan will start in his place with James Carpenter taking over as the starter at left guard. McQuistan started the first two games at left guard, but moved to tackle Sunday when Okung was hurt. McQuistan also started the last four games of the 2011 season when Okung was sidelined.
