The Spurs' night began with a bang, with Danny Green grabbing the opening tip and zooming for a left-handed dunk.

It ended with a 96-86 victory over Washington that extended the Spurs' winning streak to a season-best 10 games as they prepare to head out on their annual rodeo road trip later this week.

What should have been a Saturday night to celebrate, or at least appreciate, became a night of uncertainty when All-Star forward Tim Duncan crumpled to the floor with 3:54 left in the first half after Wizards forward Martell Webster rolled up on the back of his legs.

"I don't think I've ever seen Timmy like that before," Green said. "I've seen him hurt before — banged and bumped and bruised — but usually he gets right back up."

This time, Duncan had to be escorted off the floor with teammate DeJuan Blair under one arm and Stephen Jackson under the other. Television cameras later caught Duncan walking to the locker room on his own.

The initial diagnosis was a sprained left knee and sprained right ankle, but the full extent of the injuries likely will not be known until the 36-year-old is re-examined at some point later this week.

For now, Duncan's teammates are finding hope in the fact that he exited the AT&T Center after the game under his own power, without crutches or any other assistance.

"I don't know the ins and outs of what happened," Jackson said, "but I saw him walk out of there, so that's always good."
