TUSCALOOSA, Ala. (AP) — John Mark Stallings, son of former University of Alabama football coach Gene Stallings, died on Saturday.

The 46-year-old John Mark was born with Down syndrome and suffered from health problems related to a congenital heart defect.

In extending sympathy to the family, Mal Moore, Alabama’s athletic director, said for someone who never played or coach a game, “I think John Mark may have touched more Alabama fans than any other person ever did. I would like to thank the Stallings family for sharing their love for John Mark with all of us.”

John Mark’s story was detailed by his father in the book, “Another Season.”

Funeral arrangements are pending.
