The Los Angeles Rams quietly made a roster move on Wednesday that could indicate Kayvon Webster and Nickell Robey-Coleman may not be available on Sunday against the Saints. The Rams announced that they promoted cornerback Kevin Peterson from the practice squad, filling the roster spot left by Johnny Mundt, who was waived Tuesday.

Peterson isn’t a starting-caliber cornerback by any means, and the Rams would prefer not to play him against Drew Brees and the Saints. However, with Webster battling a concussion and Robey-Coleman recovering from a thigh injury, L.A. needs depth in the secondary.

Troy Hill is expected back for the Rams this week after missing Sunday’s game against the Vikings, which is a good sign. Dominque Hatfield and Blake Countess struggled in coverage when they filled in for Webster and Robey-Coleman on Sunday.

Peterson has played one game this season, but otherwise he’s been on the practice squad. The second-year player out of Oklahoma State was originally signed by the Bears last season after going undrafted.
