Glazer reports that the Patriots will acquire tight end Tim Wright and a draft pick.
Mankins, 32, was selected by the Patriots in the first round of the 2005 draft. He has been selected to the Pro Bowl six times in his nine-year career.
Wright was signed by the Bucs as an undrafted free agent last season. He appeared in 16 games as a rookie with eight starts. He caught 54 passes for 571 yards and five touchdowns.
The Patriots have relied heavily on tight ends in the past, using Rob Gronkowski and Aaron Hernandez effectively in 2012. The duo combined for 106 catches, 1,273 yards and 16 touchdowns that year. Gronkowski was injured most of last season and hasn't played at all this preseason. Hernandez is out of the league, having been arrested on a murder charge.
Veteran guard Carl Nicks and the Buccaneers agreed to part ways earlier this offseason.
