Bennett, who signed a three-year, $21 million deal with the Packers, said last month he thought he'd retire after the season. All 31 other teams have until 4 p.m. ET Thursday to submit a claim on him.
Considering the Packers lost star QB Aaron Rodgers with a broken collarbone, Bennett wouldn't have been much of an impact player for the team down the stretch anyway.
Bennett was ruled out for the Packers' game at the Bears on Sunday, ostensibly before the team made the decision to cut him.
Bennett had 24 receptions for 233 yards no touchdowns in his short stint in Green Bay. The Packers may look to add more depth at the tight end position in the near future, quite possibly from practice squad member Emmanuel Byrd. Bennett had base salaries of $900,000 this season, $3.6 million (plus a $2 million roster bonus) in 2018 and $5.65 million in 2019.
With a Chicago-based family and a passion for art and creativity, the 30-year-old Bennett was asked during training camp if he had considered retiring after winning a Super Bowl with New England last season.
Bennett returned with the rest of the team on October 31 and took part in practice that day. Bennett has been battling a shoulder injury recently.
Bennett's time in Green Bay came to an end Wednesday, according to ESPN's Field Yates.
Bennett was inactive during the Packers' Monday night loss to Detroit. That day, Bennett left the locker room telling reporters he wouldn't be talking with them because there was "nothing to talk about". He is the brother of the Seahawks' Michael Bennett, who has sat during the anthem. "If Marty's not, the other guys are ready to go".
