SAN DIEGO, NOV. 25 -- A couple of sure-handed catches proved costly for San Diego tight end Arthur Cox tonight.

He fumbled twice after making the receptions, the first killing a potential game-winning drive with 48 seconds remaining in regulation and the second setting up Norm Johnson's 40-yard field goal 3:01 into overtime that gave the Seattle Seahawks a 13-10 victory.

Seattle (5-6) and San Diego (5-7) combined for seven turnovers, five by the Chargers -- including three in the fourth quarter and overtime.

"Our defense created turnovers with hard hits," said Seattle quarterback Dave Krieg, who fumbled five times but lost only one. "I feel bad for Arthur Cox. Those things have happened to me. It's part of the game."

The Chargers won the coin toss to get the ball first in overtime.

Cox, who earlier caught a pass for San Diego's only touchdown, caught Billy Joe Tolliver's third-down pass in the overtime, but fumbled at the San Diego 23 when lunging for a first down.

The Seahawks ran two plays, netting one yard, before Johnson came on to kick the field goal.

"We were within his range," said Seattle Coach Chuck Knox. "Obviously, if he didn't make it, everybody would have said, 'You should have gotten a little closer.' Listen, you have to go with your gut feeling but I'm glad he made it."
