It's official ... Alabama superstar Tua Tagovailoa is goin' pro.
The 21-year-old Crimson Tide QB gave an emotional news conference on Monday ... officially ending his college career.
Tua was an absolute stud on the field ... famously filling in for Jalen Hurts mid-game to lead the Tide to a national championship in 2018.
He went on to lead the Tide under center for 2 seasons ... and was a Heisman runner-up in 2018.
Tagovailoa was putting up a Heisman-esque season in 2019 before going down with a devastating hip injury against Mississippi State.
