In the end, it appears to be much ado about (mostly) nothing.
Tuesday, after the reigning national champions had put the finishing touches on its first practice of the spring, Nick Saban confirmed that quarterback Tua Tagovailoa had suffered an unspecified injury to the thumb on his left (throwing) hand. It was expected that the quarterback would travel to Birmingham for further evaluation of the injury.
Wednesday, it was reported that the injury was believed to be just a sprain and that Tagovailoa could return to practice soon. That report proved prophetic as Tagovailoa was indeed back at practice Thursday, albeit on a limited basis.
From al.com:
Until Tagovailoa is fully recovered, Jalen Hurts will take the majority of the reps as the Crimson Tide continues its march through their 15 spring practice sessions.
The rising true junior Hurts, who has started every game but one the past two seasons, and the rising true sophomore Tagovailoa, the national championship game hero who replaced Hurts at halftime of the overtime win, are entrenched in a competition for the starting job that, barring a post-spring transfer, is expected to extend into summer camp. That said, most observers outside of the UA football program fully expect Tagovailoa, because of his proficiency in the passing game relative to Hurts, to earn the job at some point before the Tide opens the defense of their title against Louisville in Orlando Sept. 1.
