The Bengals wore shoulder pads and since Gresham didn’t play his senior year at Oklahoma because of a knee injury, it may have been the first time he’s worn them in nearly two years. Hayes, vying for camp quote of the week, offered, "I can give him plays. I can give him the mechanics, but he has to make music to it to make him play. (At the chalkboard) I’ll see how far along he is and how much he retained over the summer and go from there." Hayes is satisfied that Gresham is recovered about 100 percent from his knee injury and, like head coach Marvin Lewis, Hayes doesn’t think the eight missed practices are going to amount to much.
