Scarbrough is a freshman who initially signed in 2014 and enrolled in January. The consensus five-star prospect was injured late in Saturday's scrimmage.
Scarbrough posted Monday on his Twitter page that ''surgery went really good!'' Scarbrough was contending for playing time behind Derrick Henry and Kenyan Drake, and Saban says he's hopeful the freshman will be able to return during the season.
Saban says defensive lineman A'Shawn Robinson also sprained a knee and ankle in the scrimmage but that it wasn't anything serious.
