The Seattle Seahawks have placed left tackle Russell Okung on injured reserve, John Boyle of the Everett Herald reports.
Okung suffered a significant injury to his pectoral muscle after he was tossed to the ground by Philadelphia Eagles defensive end Trent Cole in the final two minutes of Seattle's 31-14 win last Thursday night. Okung will undergo surgery and is facing six months of rehabilitation.
Despite Okung's injury occurring via a non-football act after the whistle, there has been zero mention of a possible suspension for Cole, who has a track record of on-field actions resulting in fines, including a 2009 disqualification for throwing multiple punches at New York Giants center Shaun O'Hara.
To replace Okung on the 53-man roster, Seattle has re-signed guard Mike Gibson, who started eight games, at both guard spots, for the 2010 Seahawks, playing in over 50 percent of the team's offensive plays. Gibson was released at the end of the 2011 training camp and has had workouts with the Carolina Panthers, Dallas Cowboys and Chicago Bears this season.
Signing Gibson could mean that right guard Paul McQuistan could be moving to left tackle for the remainder of the season. McQuistan moved to left tackle for the final three plays on Thursday as backup tackles Allen Barbre and Jarriel King were inactive.
