The Patriots will probably be vague about the tight end's status, as per usual for coach Bill Belichick.
Bennett signed with the Packers as an unrestricted free agent last offseason and started seven games.
During the Packers' bye week, Bennett said on social media that he was "pretty sure" he would retire after this season, then was sidelined with a shoulder injury following the first practice after the bye.
NFL.com also reported that Bennett openly hinted on Instagram last month that he was seriously considering retirement at the end of the season. Things didn't work out exactly as expected but rejoining the Patriots puts him squarely back in the top 12 tight end conversation.
Bennett played with New England last season, winning the Super Bowl over the Atlanta Falcons in a historic comeback. It's possible one of those players could be waived once Bennett is healthy and ready to play. Bennett was clearly banged up with injuries by the end of the season but showed toughness by plowing through them to keep playing. That deal contained a signing bonus of $6.3m, of which Bennett was to receive $2.1m at the beginning of each season.
While it initially appeared as though Martellus Bennett's National Football League career could be coming to an abrupt halt, it seems as though one phone call has now changed everything. When Bennett was traded to the Patriots, in 2016, everyone seemed excited for the Gronk-Bennett combo.
