The Arizona Cardinals offensive line has been plagued with injuries and depth issues throughout the 2012 season but especially in recent weeks.
Center Lyle Sendlein tore the MCL in his left knee during the team's Week 12 loss to the St. Louis Rams.
With Sendlein -- who had previously started 80 straight games -- forced to the sidelines for the remainder of the season, Ken Whisenhunt has relied on third-year veteran Rich Ohrnberger to start at center during the team's past two contests.
Ohrnberger, who had played in all 13 games this season, injured his knee in the Cardinals' 58-0 loss to the Seattle Seahawks Sunday and was placed on injured reserve Monday. Arizona replaced his roster spot with veteran quarterback Brian Hoyer, but still wanted some depth over the final three games. And from the looks of it, they may have found it Tuesday.
News: Cardinals signed OG-C Mike Gibson to help their horribly leaky offensive line today.— Eric Edholm (@Eric_Edholm) December 11, 2012
Gibson, a former sixth-round pick by the Philadelphia Eagles, has played in just 17 career NFL games. The guard last appeared with the Seattle Seahawks during the 2010 season.
Gibson was previously cut by the Eagles in training camp.
