A decision on the availability of Denver Broncos running back Terrell Davis for Sunday's game against San Diego probably won't be made until just before game time.

Davis, who slightly separated his right shoulder Monday night in a 34-17 loss to San Francisco, was listed as questionable Wednesday on the team's injury report."He'll have to be close to 100 percent for him to play in the game," said Broncos coach Mike Shanahan. "He thinks he can get there, but I'm not really sure at this time."

Davis leads the AFC with 1,750 yards rushing, but trails Detroit's Barry Sanders (1,869) in the race for the league rushing title.
