Seahawks 34, 49ers 13

SAN FRANCISCO -- Fullback Leonard Weaver made two lengthy touchdown catches, Josh Wilson returned an interception 75 yards for a score and the Seahawks ruined Mike Singletary’s tumultuous debut as 49ers coach in a 34-13 victory.

Seneca Wallace passed for 222 yards in his third victory as a starter, including short passes turned into scores of 43 and 62 yards by his fleet-footed fullback. T.J. Duckett had an early one-yard touchdown run as the Seahawks (2-5) calmly ended their three-game losing streak.

In Singletary’s first game in charge, he couldn’t immediately fix a porous defense, but he benched quarterback J.T. O’Sullivan after three turnovers and ordered hotheaded tight end Vernon Davis off the field after a foolish penalty.
