Keenan Allen ruled out for TNF vs. Chiefs

The Los Angeles Chargers confirmed Wednesday that wide receiver Keenan Allen won't play Thursday night against the Kansas City Chiefs due to a hamstring injury.

Allen suffered the ailment in the Chargers' season opener last Sunday. Team officials are optimistic following tests that the injury isn't serious, according to NFL Network's Tom Pelissero.

DeAndre Carter replaced Allen on Sunday and contributed three catches for 64 yards and a touchdown.

Allen has spent his entire nine-year career with the Chargers. The five-time Pro Bowler signed a four-year, $80.1-million extension with the team in 2020.

Los Angeles also listed tight end Donald Parham out for Thursday, while cornerback J.C. Jackson is questionable.
