The Seahawks look like they’ll have to play without right tackle Breno Giacomini a little while longer.

Coach Pete Carroll said during an appearance on 710 ESPN on Monday that Giacomini had surgery on his aching knee. Giacomini missed Sunday’s 23-20 overtime victory over the Texans as a result of the injury, leaving the Seahawks without three of their original starting linemen with left tackle Russell Okung and center Max Unger also on the sideline.

Carroll said it was a cleanup procedure to remove loose bodies in the knee. Carroll offered no specific timetable for Giacomini’s return, but hopes that it will be weeks rather than a month or more before Giacomini is able to return to the lineup.

The Seahawks started seventh-round rookie Michael Bowie in Giacomini’s place. The offensive line struggled against the Texans, allowing Russell Wilson to be sacked five times and hit twice as often. The group finished better than it started, though, and Bowie will likely get a few more chances to acclimate himself to the NFL game in the coming weeks.
