Looks like a candidate to be the backup Mike who can play special teams. 6'2 245 4.78, Brugler rated him as an UDFA:
SUMMARY: A one-year starter at Indiana, Covington lined up inside in the Hoosiers’ dual-linebacker scheme, playing next to Tegray Scales. He moved between several positions his first two seasons in Bloomington and entered 2017 with one career defensive start, but quickly adapted and played like a veteran. While very average from a size/speed perspective, Covington competes with a physical appetite and fills with power. With his lack of experience at the position, he needs to continue and develop his awareness, but he rarely took himself out of plays on tape, including in coverage. Overall, Covington might not have a high ceiling in the NFL, but he flashes the competitive chops and enough speed to see the field on special teams.
GRADE: Priority Free Agent
