The Ravens signed wideout Joe Morgan, the team announced on Wednesday. They also placed Smith on injured reserve.
Morgan appeared in 21 games over four years with the New Orleans Saints -- missed all of 2013 with a knee injury and was also suspended for unspecified reasons -- catching just 14 passes for 471 yards and three touchdowns. Morgan displayed big-play ability as a rookie, but hasn't been the same since his knee injury. He has been cut twice by the Saints in 2015.
