With starting wide receivers Malcolm Floyd and Legedu Naaneee doubtful for Sunday's game with hamstring injuries, the San Diego Chargers have promoted wide receiver Seyi Ajirotutu from the practice squad.

Linebacker Kion Wilson was placed on injured reserve with an ankle injury the team announced occurred during Friday's practice.

A 6-3, 211-pound rookie free agent out of Fresno State, Ajirotutu caught 7 passes for 145 yard for the Chargers during the pre-season and has been on their practice squad the first six weeks of the season.
