TUSCALOOSA, Ala. (AP) — Alabama defensive line coach Bo Davis has resigned.

Crimson Tide coach Nick Saban announced the resignation on Friday in a two-sentence statement. He didn't elaborate on reasons behind the decision.

Davis began his second stint coaching the line for Saban in 2014 after three seasons at Texas. He also was Saban's defensive line coach from 2007-10.

Davis's line was one of the strengths of Alabama's team during last season's national championship run. It featured Jarran Reed, Jonathan Allen and A'Shawn Robinson, an All-American and Outland Trophy finalist.

All three were All-Southeastern Conference picks.

Davis was named National Recruiter of the Year by Scout.com earlier this year.
