Andrew Luck might FOR REAL never play football again ... at least that's what Jim Irsay believes, with the Colts owner saying this week he thinks the QB will stay retired after all.
"I think that door's closed," Irsay told NFL.com.
You'll recall ... Andrew had one of the most shocking retirements in NFL history -- calling it quits just days before the 2019 season officially began.
Some thought it was a rash and impulsive decision ... and believed he'd return to action at SOME point.
But, Luck has remained retired since making the choice .
