In an interview with SiriusXM NFL Radio on Monday morning, Winslow said he was told by the team that his services no longer are required. Winslow said he was told the Bucs will attempt to trade him.
"They're not looking for my services this year. (Coach Greg Schiano) said he'd help me out with a trade. It's kind of shocking, but that's what it is," Winslow said.
The veteran tight end worked out for the team last week, and the Bucs are expected to sign him to a contract sometime Tuesday, a league source told ESPN NFL Insider Adam Schefter.
Winslow, meanwhile, said he was told by the Buccaneers that part of the reason for the decision was that he had not been taking part in offseason workouts with the team.
"(Schiano was) kind of upset that I wasn't there with the team working out in the offseason and then the first week of OTAs. You know, look, I've been there the last three years and I've had a successful career so far. You just don't get rid of one of your best players because of that," Winslow said.
Schiano hasn't been shy about shaking up a roster that produced a 4-12 record last season. Schiano previously released safety Tanard Jackson, with team officials saying it was because the team was unhappy with how Jackson was approaching the offseason.
Winslow, 28, joined the Bucs in 2009 through a trade with Cleveland. Although a sore knee prevented him from practicing frequently last season, Winslow appeared in all 16 games and caught 75 passes for 763 yards and two touchdowns.
The Colts released Clark, who will turn 33 next month, on March 9 as part of a massive veteran purge following the release of franchise icon Peyton Manning.
Clark spent nine years with the Colts, catching 427 passes for 4,887 yards and 46 touchdowns. He also became the second tight end in NFL history to have 100-plus receptions in a season (2009). He was chosen for the Pro Bowl in that year.
