A couple of September additions are now subtractions.
The Patriots announced the release of offensive lineman Braxton Cave and tight end Matthew Mulligan on Thursday.
Cave was claimed off waivers by the Patriots from Cleveland on Sept. 1. He was originally signed by the Browns as a rookie free agent out of Notre Dame. Cave played in 48 games for Notre Dame, including 35 starts at center.
Mulligan was signed on Sept. 3 and is a veteran of four NFL seasons with the Jets and Rams. He went to camp this summer with the Packers but was released on Aug. 31. Mulligan has played in 50 NFL games with 20 starts and has 14 receptions for 144 yards and one touchdown.
Patriots tight end Rob Gronkowski has been listed as limited on the team's practice report this week, and it's unclear at this time if the release of Mulligan has anything to do with Gronkowski's availability for Sunday's season opener against the Bills.
MassLive reports that the team is set to re-sign FB James Develin.
