ST. LOUIS (AP) St. Louis Rams coach Jeff Fisher said the organization has been in contact with the league for possible solutions after two players slipped on concrete bordering the field the past two weeks.

49ers running back Reggie Bush planted both feet on the concrete and landed on his backside slowing down after a punt return in the first quarter Sunday. He slid into the padded wall of the stands. Bush was carted off with a left knee injury after the play.

Browns quarterback Josh McCown was driven out of bounds and banged his left arm or shoulder when he slid into the wall two weeks ago, but didn't come out of the game.

Fisher said there had been ''hundreds'' of games at the Edward Jones Dome without an issue until recently. The coach said many other stadiums in the league have concrete surfaces bordering the field.
