Former LSU quarterback Y.A. Tittle died on Monday morning at the age of 90, according to a report by the Marshall News Messenger.
The sports information department at LSU, Tittle's alma mater, confirmed his passing, noting that the National Football League icon was peacefully surrounded by family and friends.
Tittle had memory problems later in life related to dementia.
During his 10 seasons in San Francisco, Tittle amassed a 45-31-1 record and put up some mind-boggling numbers. Before the 1961 season, Tittle's esteem was low to the point that the 49ers exchanged the 34-year-old QB to the Giants for a new kid on the block hostile lineman (Lou Cordileone).More news: Carson Wentz, Eagles soar to new heights with emphatic win over Cardinals
Tittle was part of the famous "Million Dollar Backfield", which consisted of himself, fullback Joe Perry, and halfbacks Hugh McElhenny and John Henry Johnson.
Tittle was the first professional football player to be featured on the cover of Sports Illustrated.
The photo was taken in 1964, Tittle's last season, by Morris Berman of the Pittsburgh Post-Gazette.
When Tittle left San Francisco, he went to NY to play for the Giants for the last four seasons of his career.
