Robertson (hip) is active for Sunday's game against the Bengals, according to Paul Gutierrez of ESPN.com.
Robertson didn't play against the Chiefs last week and didn't practice Wednesday, so his status for the weekend was looking grim, but he recorded a limited practice Thursday and didn't have restrictions Friday, so he's been cleared as a result. His presence boosts the depth of the cornerback corps, as Brandon Facyson (finger/hamstring) is questionable while Keisean Nixon (ankle/foot) is out.
