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.

Cooper spent three seasons at Tulane before transferring to UH, where he had 46 tackles, nine tackles for loss and 3.5 sacks last season. In his 51-game collegiate career, Cooper totaled 119 tackles, 26 tackles for loss, 14 sacks, eight passes defensed, a forced fumble and a fumble recovery.

On Monday, the Lions signed tight end Luke Deal, wide receiver Malik Taylor and defensive lineman Raequan Williams. In a corresponding move, the team waived undrafted free agent tight end Caden Preiskorn. The team's roster is currently at 90 players, as it received an exemption for sixth-round pick Ahmed Hassanein.

As football fans gear up for the 2025 NFL schedule release Wednesday, several media outlets are selecting their top must-see games of the season. NFL.com’s Kevin Patra ranked the matchup between the Detroit Lions at the Philadelphia Eagles as his second-most anticipated game of the year.
