Chargers' Slater likely out for season, Bosa week-to-week with groin injury

Los Angeles Chargers left tackle Rashawn Slater is believed to be lost for the rest of the season due to a biceps injury, head coach Brandon Staley said Monday, according to Fernando Ramirez of The Sporting Tribune.

Staley added that star pass-rusher Joey Bosa is week-to-week with a significant groin injury, per ESPN's Lindsey Thiry.

Slater reportedly ruptured his biceps tendon in Sunday's loss to the Jacksonville Jaguars, a source told NFL Network's Tom Pelissero. Bosa also exited the game and didn't return.

The Chargers have been bit by the injury bug in recent weeks. Star quarterback Justin Herbert is playing through fractured rib cartilage, while wide receiver Keenan Allen and cornerback J.C. Jackson missed Week 3 due to hamstring and ankle injuries, respectively.

Additionally, receiver Jalen Guyton is also out for the season after suffering a torn ACL, Staley noted. Guyton has caught two passes for 64 yards this season, including a 54-yard catch from Herbert on Sunday.

The 13th pick in last year's draft, Slater made the Pro Bowl during his rookie season. He's also started 19 games for the team.

Veteran Storm Norton will likely fill in at left tackle for Slater.
