Denver Broncos place Marvin Austin on Injured Reserve Posted Aug 20, 2015 The Denver Broncos were awarded TE Jake Murphy off waivers from Cincinnati on Thursday. To make room, they placed NT Marvin Austin Jr. on injured reserve. Austin has missed nearly all of training camp because of a groin injury. With the emergence of sixth-round pick Darius Kilgo in his stead, Austin slipped to the fourth team while he dealt with his injury. (Denver Broncos)
