A source with knowledge of the situation says the Raiders waived receiver Derek Hagan to make room on the team's 53-man roster for newly-signed wideout T.J. Houshmandzadeh.
Also, the Raiders are putting injured cornerback Chris Johnson, who has been out since Week 3 with hamstring and groin issues, on season-ending Injured Reserve.
The Raiders have yet to confirm such moves or announce any roster moves.
Hagan made the team as a free agent in training camp and has caught 11 passes for 114 yards in six games.
Hagan led the Raiders with 224 yards receiving on a dozen receptions in the preseason but has only two receptions in the past two games -- one against Houston and none against Kansas City.
He was originally a third-round pick of Miami in 2006. He spent three seasons with the Dolphins and the past two with the New York Giants.
Oakland signed Hagan as an unrestricted free agent on Aug. 7.
