The Bucs released defensive end Kevin Carter two weeks ago with an understanding every effort would be made to retain him.

While talks continue, Carter remains open to other suitors, including the Raiders, with whom he will visit on Wednesday. We've learned the veteran free agent is in route to Oakland as of this writing for a meeting with the team, one of several to express interest in the 34-year-old. The trip coincides with Carter's trip later this week to Hawaii where union representatives are holding an annual meeting.

The status of Carter's negotiations with the Bucs is unclear. Carter was released on Feb. 27 a few days before he was scheduled to be paid a $2-million roster bonus. He had three years remaining on his deal and was slated to earn $3.8-million in base salary this fall.

The Bucs' interest in signing Carter is obvious. They would have a significant void at left defensive end if the veteran moved on. Gaines Adams is capable of playing there, but he was the starter at right end last season. Greg White, though very successful in his first full NFL season in 2007, has never been a full-time starter and has played almost exclusively at right end. The Bucs also signed Chiefs free agent end Jimmy Wilkerson, but he is expected to be more of a reserve player who will provide depth.
