He very well could be ... 'cause TMZ Sports has learned former Heisman winner Johnny Manziel is currently in talks with Fan Controlled Football to make a return to the gridiron!!

29-year-old Manziel was one of the most notable players in the FCF's inaugural season ... suiting up under center for the Zappers for three games.

Our sources feel confident Manziel will be back in season two ... at least for a few games.

But, here's where it gets interesting -- we're told Johnny would NOT be returning to the Zaps for the upcoming season ... as he's dying to play for Druski's new team.

In fact, Johnny went to Instagram early Friday morning to express his interest in joining the comedian's squad ... saying, "Only coming out of retirement for @Druski2Funny and Shoulda Been Athletics."

We broke the story -- Druski was announced as the newest owner of the defending champion Wild Aces earlier this week ... name-dropping Manziel as one of the main reasons he decided to get involved in the league.

It would be a full-circle moment for Druski ... and considering how passionate he is about the team, he's gotta be stoked about the possibility of having Manziel on board.
