Former NFL tight end Martellus Bennett confirmed Monday he will not come out of retirement to play alongside his brother, Michael Bennett, with the New England Patriots.

Bennett made the announcement on Instagram and pointed toward his commitment to his Imagination Agency and working with children as the reasoning behind his decision to stay retired:

"This is why I can't come out of retirement. I would love to play ball with my brother it would truly be a dream come true. But my biggest dream is to change lives with my creativity and that is what I am currently doing @theimaginationagency these kids don't need another athlete to look up to or to aspire to be there's plenty of inspiration out there for that. I want to inspire the next wave of creatives. The storytellers. The engineers. The designers. The doctors. The filmmakers. The composers. Tech moguls. And maybe a few athletes who like me never felt like they belonged in a locker room. I was never one of the guys guys most of my teammates would tell that. I've always been a creative who enjoyed competing. I'm playing the game that I was made to play and it's the most fun I've ever had. Scoring touchdowns winning a super bowl has never made me feel the way seeing kids/families/people enjoying things I have created. I'm doing my life's work fulfilling what I believe to be my life's purpose. I hope everyone finds something that makes them as happy and as fulfilled as I have with my work @theimaginationagency I appreciate all of the love but this is waaaaayyy bigger than the game of football."

After the Patriots acquired Michael Bennett in a trade with the Philadelphia Eagles this offseason, ESPN's Adam Schefter reported Martellus had interest in coming out of retirement to join his brother, but Michael called it "fake news" during a discussion at Princeton University.

The 32-year-old Martellus Bennett retired following the 2017 season, which was his 10th year as an NFL player.

During his career, Bennett played for the Dallas Cowboys, New York Giants, Chicago Bears, Green Bay Packers and Patriots.

After registering 55 receptions for 701 yards and seven touchdowns for the Pats in 2016, Bennett signed a three-year deal with the Packers. The Packers waived Bennett after just seven games when he failed to disclose a medical condition.

That allowed the Patriots to claim Bennett off waivers, but he appeared in just two games for the Patriots before being placed on injured reserve.

Bennett won a Super Bowl during his first season with the Patriots, and he was also named to the Pro Bowl in 2014 with the Bears when he set career highs with 90 receptions for 916 yards to go along with six touchdowns.

While the Pats won't be getting Martellus back, trading for Michael Bennett may still be a beneficial move since the three-time Pro Bowler and one-time Super Bowl champion is coming off a nine-sack season with the Eagles.
