Chargers' offense is beat up

San Diego Chargers star tight end Antonio Gates didn’t practice Wednesday because of a toe injury he suffered in a loss at St. Louis on Sunday. He could miss Sunday’s game against New England.

Receiver Legedu Naanee didn’t practice Wednesday because of a hamstring injury that kept him of the Rams’ game. Naanee will be needed because No. 1 receiver Malcom Floyd will likely not play against the Patriots with a hamstring injury. Running back Ryan Mathews was kept out of Wednesday’s practice because of a nagging ankle injury.

Mathews is expected to play, but if Gates, Floyd and Naanee are out, San Diego will be hard pressed to score points against the Patriots.

  • It appears Kansas City defensive end Tyson Jackson is making strides to getting back on the field. He practiced fully Wednesday. He has been out since Week 1 with a knee injury. Receiver Chris Chambers (finger) and right tackle Ryan O’Callaghan (groin) also practiced fully for the Chiefs.

  • The Broncos signed tight end John Nalbone and defensive lineman Mitch Unrein to the practice squad.
