ALLEN PARK, Mich. (AP) – The Detroit Lions have signed undrafted rookie linebacker Raphael Kirby and removed tackle Corey Robinson from the active-physically unable to perform list. Detroit also announced Monday that it has waived linebacker Dominique Tovell. Kirby played four years at Miami, making 19 starts. He was the leading tackler for the Hurricanes when he went down with a season-ending right knee injury last October.
