Seattle Seahawks guard John Moffitt is expected to undergo surgery on his left elbow and miss the next two to three weeks.

Moffitt's elbow has been causing problems for him recently and forced him to leave practice early on Thursday. His left arm was in a sling during Friday's walkthrough.

Coach Pete Carroll said Moffitt is likely to undergo surgery to clean up some "loose bodies" in his elbow. Deuce Lutui (luh-TOO-ee) will start in place of Moffitt at right guard for the team's preseason opener Saturday against the Tennessee Titans. Rookies J.R. Sweezy and Rishaw Johnson are also expected to see time at the position.

Carroll said the injury is not likely to force Moffitt to miss the season opener against Arizona.
