The Los Angeles Chargers are still tinkering with their overall roster ahead of the start of the 2025 regular season. On Sunday, the team brought back a wide receiver it had all summer and added a new running back to the mix after holding tryouts. Luke Grimm, an undrafted wide receiver out of Kansas, was a popular pick by the fanbase to stick with the team this year. The Chargers have decided to add him back to the practice squad along with running back Amar Johnson.
