Veterans made their way to Detroit Lions training camp in Allen Park, Michigan, over the weekend with media flocking to ring in the dawn of the new season for the Motor City's NFL franchise. The Lions have big goals ahead of them with a daunting schedule on the horizon and the return of several key players from injury.

Detroit Lions head coach Dan Campbell mentioned undrafted free-agent edge rusher Keith Cooper recently and that now makes the rookie someone to watch in training camp.

With the retirement of star center Frank Ragnow, the Lions were left trying to figure out how they would fill the void left behind. As it stands, entering camp, a second-round rookie --who had never played a game at the position-- is in the mix to take the job in Week 1.

Dan Campbell walked off the field following last season's NFL Divisional Round playoff loss to the Washington Commanders without many answers. An unexpected loss at Ford Field as the NFC's top seed following a franchise-record 15 regular season wins meant nothing after a 45-31 setback.

Two Detroit Lions backups, defensive tackle Roy Lopez and running back Sione Vaki, are expected to be out for a few days, coach Dan Campbell said.

Lions defensive end Aidan Hutchinson is practicing at training camp, nine months after a broken leg ended his 2024 season.

Head coach Dan Campbell talks to the press about the importance of running back David Montgomery in Detriot Lions' offense.

OUTLOOK: An ACL has a very reliable recovery, but takes about 11 months to return to play. He should be ready for next season if this is an uncomplicated ACL repair.
