The Baltimore Ravens have gone to the Arena League to add more depth to their secondary.
The Ravens signed defensive back Marrio Norman and waived wide receiver Gerrard Sheppard.
Norman, who turns 28 next month, played the past two seasons for the Cleveland Gladiators and Georgia Force. At 6-foot-1, 205 pounds, Norman played both safety and cornerback in college while at Coastal Carolina.
He had tried out for the Ravens earlier this year but wasn't signed. The Ravens have grown thin at cornerback since Aaron Ross suffered a season-ending Achilles injury and Lardarius Webb has missed more time than expected with a back injury.
Sheppard, who played at nearby Towson in college, spent last season on the Ravens' practice squad.
