Rob Gronkowski Returns To Football Field, Nails Field Goals With Mojo Muhtadi

Gronk is BACK on the football field!!!

Recently retired NFL superstar Rob Gronkowski will have Tampa Bay Buccaneer fans drooling over the idea of a comeback ... after the tight end was spotted on the gridiron in Orlando over the weekend.

It's a clip that will have folks wondering if the 4-time Super Bowl champ has the itch to return to his day job ... considering he's still in incredible shape.

But, don't expect the 33-year-old to pull a Tom Brady and return to the league just yet ... 'cause he wasn't running routes and catching passes -- he was lining up for some field goals with his buddy/TMZ Sports TV show co-host Mojo Muhtadi.

The guys were at Camping World Stadium to check out a Pop Warner football game ... and we're told Gronk decided to hop on the gridiron and show off his boot.

Gronk's no Justin Tucker, but it doesn't matter -- he was still able to get the pigskin between the pipes for a successful attempt.

Gronk also had some fun talking to some of the kids at the game ... even joining their huddle for a cute moment.
