During a Tuesday appearance on the Jim Rome radio show, otherwise known as "The Jungle," Bears quarterback Rex Grossman said he's headed to Cincinnati Thursday for a visit as the Bengals search for a backup quarterback, and former Bills starter J.P. Losman is also expected at some point.
The Bengals confirmed Tuesday's visit of another No. 2 candidate with the arrival of 49ers quarterback J.T. O'Sullivan.
O'Sullivan, 29, is coming off his busiest season since the 2002 Saints drafted him in the sixth round out of Cal-Davis. He threw 220 of his 246 career passes and completed 57.3 percent last year for a 73.6 passer rating with eight touchdowns and 11 interceptions in nine games. In 14 career games he's thrown nine touchdowns and 13 interceptions.
After wide receiver T.J. Houshmandzadeh agreed with Seattle and Derrick Ward agreed with Tampa Monday night, the Bengals still have receiver and running back as priorities as they hosted long-time Jets receiver Laveranues Coles on Tuesday.
They are also bringing in a pair of restricted free agent fullbacks for visits, Naufahu Tahi of the Vikings and John Kuhn of the Packers.
The Bengals have had high regard for the 6-0, 254-pound Tahi for a long time, ever since they signed him as an undrafted free agent out of BYU in 2006. He pushed incumbent Jeremi Johnson until final cuts and ended up on the practice squad. He was released later that season, but surafced in Minnesota last year and got some quality time blocking time for Pro Bowl running back Adrian Peterson while making 16 catches for 37 yards.
Since both Kuhn and Tahi were college free agents, they wouldn't cost compensation as the Bengals try to find the successor to Johnson after they cut him in the middle of last season.
In Seattle, former Bengal T.J. Houshmandzadeh opted to wear No. 18, his number at Oregon State.
