Tim Tebow comforted and prayed over a fan who suffered a seizure after the star's Arizona Fall League game on Tuesday ... and TMZ Sports has footage from the scene.
Tebow -- still in uniform -- was signing post-game autographs for fans when a man named Brandon began to suffer a seizure and collapsed onto the concrete.
Tebow waited with the man for 15 minutes while paramedics rushed over -- with Tim offering words of encouragement until help arrived. In the video, you can hear Tebow say, "Hang in there buddy."
Witnesses at the scene tell us Tebow also prayed over the man -- and even joked around with the guy to keep him in good spirits.
When Tebow was confident the situation was under control he squeezed the man's hand and promised he would be in touch.
So far, no update on the man's condition.
