Y.A. Tittle
1926 - 2017
In the above pic, Tittle just had the slobber knocked out of him by John Baker of the Pittsburgh Steelers (perhaps you've heard of them?

), after throwing a Pick Six interception. He suffered a concussion, and a cracked sternum, but managed to finish the season, his 17th, and, final.
That photograph became one of three that hung in the lobby of The Press Photographers Association, alongside the Raising Of The Flag On Iwo Jima, and the Hindenburg Disaster. A copy now hangs in the Football Hall Of Fame.
