Russell Okung injures foot

SEATTLE -- Seahawks offensive tackle Russell Okung was carted off the field and taken to the locker room with a foot injury near the end of the first quarter of Sunday night's 29-3 win over the San Francisco 49ers.

Okung returned to the Seattle sideline late in the second quarter and did some drills near the Seahawks bench, but the team announced he would not return. Paul McQuistan moved from left guard to Okung's left tackle spot and James Carpenter came in to play left guard.

Seattle did not have another offensive tackle on the active roster because rookie tackles Alvin Bailey and Michael Bowie were among the inactives Sunday night.

McQuistan had a tough time with 49ers outside linebacker Aldon Smith, who sacked Wilson twice after getting by McQuistan, but Seattle led 5-0 at the half.

The first half was delayed for an hour late in the first quarter because of lightning and storms in the area.
