The Bears have waived/injured veteran linebacker Brian Iwuh and promoted linebacker Patrick Trahan from the practice squad to take his place.
Iwuh, a six-year veteran who led the Bears in special teams tackles with 14 this season, suffered a hamstring injury in Sunday's 25-20 loss to the Oakland Raiders in Oakland. In 2010, he was tied for second with Garrett Wolfe in special teams tackles with 18. He also started in place of Lance Briggs against the Seahawks and led the Bears with 12 tackles.
The 6-2, 236-pound Trahan, an undrafted free agent from Mississippi in 2010, spent the 2010 season on the Tennessee Titans practice squad. He signed with the Bears in January.
In the "waived/injured" procedure, another NFL team can claim Iwuh. If he goes unclaimed on waivers, he will revert to the Bears' injured reserve list.
