Robinson was injured in the third quarter of Saturday’s win at Tennessee.
Saban didn’t offer any other information about the injury, according to Andrew Gribble of al.com.
Robinson, a 6-foot-6, 323-pound true freshman from West Monroe, La., was a five-star prospect, according to Rivals.com, and was rated as the top offensive tackle in the class of 2014.
He has been one of the best freshman offensive linemen in the country and had started all eight games for the 7-1 Crimson Tide.
Alabama is on a bye this week, but if Saban’s timetable is correct, Robinson would be out when the No. 3 Crimson Tide visit No. 16 LSU on Nov. 8.
