The Oakland Raiders have signed Derek Hagen.

Hagen caught 11 passes for 114 yards in six games for the Raiders last season before being cut to create space for T.J. Houshmandzadeh. Hagen went on to catch 13 balls for 138 yards and a touchdown with the Bills.

Denarius Moore (hamstring) and Jacoby Ford (foot) are unlikely to play on Monday against the Chargers.
