Dak Prescott says he's healthy and ready to ball out for the Dallas Cowboys in 2021 ... and thanked Alex Smith for giving him hope after suffering his gruesome ankle injury.
The 27-year-old QB was all smiles at his big contract signing event with Jerry Jones on Wednesday -- and for good reason, he just signed a 4-year deal worth up to $164 million!!!
But, the big question on everyone's mind ... will Dak be 100% when he takes the field in September after that horrific compound fracture and dislocation of his right ankle he suffered during the 2020 season?
