George Kittle Open To Future In WWE, 'Sounds Fun!'

George Kittle is nowhere near done playing football, but when the time comes to hang up the spikes, he tells TMZ Sports he definitely wouldn't mind transitioning to the WWE!!!

The 49ers star didn't mince many words when the topic was brought up out in Arizona earlier this month ... saying he believes he's got the personality to smoothly jump from the NFL to the wrestling world if and when the time comes.

"Sounds fun!" he told us.

Of course, Kittle is a huge WWE fan ... he's been spotted at events like "Monday Night Raw" through the years, despite the taxing demands of being a professional football player.

The All-Pro tight end even put his wrestling skills on display recently at the NFL's Pro Bowl ... exchanging some moves with his teammate, Kyle Juszczyk.

Kittle's transition to the squared-circle would be pretty awesome ... but it would not be the first time we've seen an NFL tight end try his hand in the WWE.

Rob Gronkowski appeared at WrestleMania 33 ... where he helped his friend and former WWE star Dean "Mojo" Muhtadi win the Andre The Giant Battle Royal.

Gronk had one of the best spots despite not actually competing ... bulldozing through Jinder Mahal and paving the way for Mojo to eliminate Jinder, winning the match.
