Saints RB Ricky Williams sprained his right elbow in Sunday's loss at San Francisco and Coach Mike Ditka isn't sure when Williams will be able to play again.

Team doctors were scheduled to examine Chmura, 30, yesterday to determine whether it's safe for him to continue playing. . . .

Seahawks starting QB Jon Kitna and LB Chad Brown, who led the team in tackles last season, are expected to return for Sunday's game at Pittsburgh, Coach Mike Holmgren said. . . .
