Six days after sustaining a concussion, wide receiver Stephen Hill was medically cleared for contact Saturday and is expected to play Monday night when the New York Jets face the Atlanta Falcons at the Georgia Dome. But the Jets could be without their leading receiver, tight end Kellen Winslow, who didn't practice and is listed as questionable. Winslow, hampered by chronic knee pain in recent years, usually gets a day off during the week, but he sat three of four practices this week.
