ALLEN PARK -- The Detroit Lions are making more roster moves following last week’s rookie minicamp. They are signing rookie edge defender Keith Cooper Jr. and waiving interior offensive lineman Leif Fautanu.

Cooper is a 6-foot-3, 280-pound defensive end who played collegiately at Tulane and then Houston, going undrafted after completing his Cougars career. He primarily played DE for Houston, racking up 3.5 sacks in his final year. He's a crush-the-can style of EDGE that the Lions favor, and that showed in Friday's rookie minicamp session.

The Lions signed DT Raequan Williams, WR Malik Taylor and TE Luke Deal after they attended rookie camp on tryouts
