Austin Mack has sat back for the better part of three seasons at Alabama in a backup role, just waiting for his opportunity.
On Saturday on the road against Vanderbilt, it looks like he's finally going to have his moment.
Per ESPN's Pete Thamel, the current expectation is that Mack will start over banged-up Keelon Russell in Nashville on Saturday afternoon. Russell is expected to be available, but more in an emergency situation, with the senior backup taking the reins:

Austin Mack reportedly set to make his first career start for Alabama at Vanderbilt
Russell suffered an ankle injury during last week's win at LSU. The injury occurred during the third quarter, but after a stint in the medical tent, Russell returned to the game without missing a snap. He threw three touchdown passes from there to help Alabama earn a 31-13 win in a pivotal spot in Baton Rouge.
Kalen DeBoer called the sophomore phenom "day-to-day" during his Monday press conference, and despite him being listed as "probable" on both Wednesday and Thursday's availability reports, Mack has been trending to start most of the week with increased practice reps.
The reason for Russell being listed as "probable" and ultimately not starting is so that he can be available to play if necessary. So if Mack goes out there and is abysmal and Alabama falls behind, maybe the risk is worth it with Russell at that point. Or if Mack gets hurt, the Crimson Tide could turn to Russell instead of freshman Jett Thomalla.
Make no mistake: Russell could play tomorrow. He's hurt, but he could go out there and play. This move is strictly to avoid this issue lingering for weeks on end, and the staff believes a healthy Mack gives them a better chance this week than a banged-up Russell.
If Mack can play well and navigate this game, it would give Russell two weeks to heal up before the Iron Bowl. If Alabama trusts Mack to start on the road against Vanderbilt, they would trust him again next week against Chattanooga at home.
This will give Mack the showcase he has wanted. The expectation is that Mack will enter the Transfer Portal after the season, with Russell set to return to Tuscaloosa for his junior season. This tape will be critical for his ability to command a hefty payday and a guaranteed starting job somewhere else. People will be watching to see how he handles this spot.
Russell's injury is precisely why you want to have a quality backup quarterback. There was always a chance that the Crimson Tide would need Mack at some point this season, and his team appears to have finally arrived.
There aren't many teams that have a backup with as much experience in the system as Mack. He has worked under DeBoer's tutelage for four years now. He knows everything there is to know about the playbook and should be more than capable of stepping up for his team.
This is a key spot for Alabama. While the Tide sits at No. 3 in the College Football Playoff ranking, a road loss to 4-5 Vanderbilt would cause a significant drop in the polls. The committee has proven unafraid to make significant course corrections week-to-week. Alabama can't afford to lose this game.
Mack is capable of leading the Tide to the road win, but it would be a big help if the ground game can get going and Kane Wommack's defense can shut down the Commodores' attack.
