Jay Graham has resigned as Alabama special-teams and tight ends coach to "seek professional help" and "gain a better understanding of mental health."
He was introduced by the school less than two months ago.
In a statement on Twitter, Graham explained his decision.
"The events of the past year have taken a toll on millions of people around the world, not only in lost loved ones or lost jobs but in unprecedented anxiety and mental health.
"I am taking time away from football to seek professional help immediately, gain a better understanding of mental health and spend time with loved ones.
