Michael Campanaro, WR (waived-injured designation): Campanaro, the third-year wide receiver who was thought to be the team's top option at kick returner, had an MRI today and was diagnosed with a calf strain. Campanaro, the former River Hill standout who was limited to eight games over his first two NFL seasons, has been hampered by the injury in recent days. He also missed most of the offseason minicamps with a calf strain. With the Ravens waiving Campanaro, it increases the likelihood that the team signs free-agent returner Devin Hester.
