At San Francisco, 49ers running back Frank Gore and tight end Vernon Davis were injured on the same wacky play in a 38-24 loss to Philadelphia.

Gore fumbled and apparently strained a muscle in his abdomen while trying to stretch over the goal line late in the third quarter. Philadelphia's Mike Patterson, a 292-pound defensive lineman, picked up the ball and lumbered 98 yards downfield for the longest fumble return for a touchdown in Eagles history.

Davis, the sixth overall pick in the draft, got hurt, while trying to chase down Patterson from behind. Davis was taken off the field on a cart and is expected to miss four weeks.

``I was trying to tackle him and I just pulled up,'' Davis said. ``I didn't make any contact. I felt something and just fell down.''

Gore walked to the locker room after the play and the extent of his injury won't be known until Monday. Coach Mike Nolan said he was questionable for next week.

The Eagles were without receiver Donte' Stallworth, who was a late scratch because of a hamstring injury.
