Oakland?s star receiver Randy Moss is doubtful for Sunday?s game against the Bills after suffering bruised ribs and a strained groin versus the Chargers last Sunday. He didn't practice in the afternoon session. While walking slowly to his car afterward, Moss said he was feeling "OK." "We'll know Sunday," Moss said of whether he will be ready to go against the Bills. Coach Norv Turner wasn't ready to rule out his star receiver. "We'll see each day. If he recovers and can run full speed, we'd love to have him," said Turner, after spending several minutes after practice talking to 76-year-old owner Al Davis, who was wearing his signature shiny white sweatsuit and using a walker to get around.
