The two teams are still ironing out the language of the trade.
The Bucs announced they have signed former Colts tight end Dallas Clark.
Winslow had 75 receptions for 763 yards and two touchdowns last season with the Bucs. He averaged 10.2 yards per reception and played in all 16 games last year.
Earlier in the day, Winslow told SiriusXM radio Monday that first-year coach Greg Schiano was ''kind of upset'' that Winslow has not been working out with the team and told the player that he would be dealt.
Clark spent nine seasons with the Indianapolis Colts. He has 427 career receptions for 4,887 yards and 46 touchdowns.
