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.
Raiders Pro Bowl left guard Kelechi Osemele, running back Taiwan Jones and safety Brynden Trawick are currently enjoying their offseason in New Zealand.
But a few videos they posted going white-water rafting and bungee jumping left head coach Jack Del Rio a bit anxious.
"Anxiety level went up a bit thinking of my BIG pro bowl LG on the rapids!!" Del Rio tweeted Monday. "Can't leave out Brynden or Taiwan either ... have fun and be safe"
Osemele has posted a handful of photos and videos from the trip, including one of a raft capsizing with the caption: "It got real out there!!! Category 4 Rapids #NewZealand." Another showed the 6-foot-5, 333-pounder doing a backflip off a bungee platform with the caption: "Just did a backflip off the highest swing in the WORLD!!!!!!! Crazy!!! #LivingLife"
Trent Richardson is reportedly in some trouble.
Richardson was arrested on Thursday night for domestic violence, according to TMZ Sports.
The former running back was taken into custody on a third degree charge, the report states, with bail being set for $1,000.
The arrest was made in Hoover, Alabama.
The Browns selected Richardson with the third overall pick in the 2012 draft.
He was traded to the Colts in 2013 and played for Indianapolis in 2014.
He signed with the Raiders in 2015 and appeared in three exhibition games, but did not make the team.
The 26-year old was cut by the Ravens last August.
