Johnny Manziel has officially been invited to join an independent pro football league in April -- a league that already has commitments from ex-NFL stars like Greg Hardy and Kellen Winslow Jr.
TMZ Sports spoke with a rep for The Spring League who says Kellen and Hardy are 100% committed to play in the 4-team league which will primarily feature NFL vets and "younger talent."
The league is expecting to have reps from all 32 NFL teams at their games and believe it will serve as a showcase for guys trying to get in the league.
