The Cincinnati Bengals are dealing with more injuries to their cornerbacks, and one is headed to injured reserve. Shaun Prater, a 2012 fifth-round draft pick out of Iowa, suffered a knee injury that will land him on season-ending IR, a source with knowledge of his situation said Saturday. Prater will undergo surgery to clean up his knee at a later date. The rehabilitation, centered around his patella, could take up to four months, but he's expected to be ready for the offseason conditioning program. Source: NFL.com
