Despite being heckled by fans during his post-game interview after his Arizona Fall League debut, Tim Tebow stuck around to sign autographs for fans braving the heat.
One fan in the front row suddenly dropped, prompting others to yell for a medic.
Tebow rushed to the side of the fan, who was convulsing and foaming at the mouth, while EMTs administered care.
While waiting for the fire truck to arrive, the fan went limp. The crowd fell silent while waiting for the sirens.
Tebow reached over, put his hand on the fan and said a quick prayer.
Seconds later, the fan gasped for air and the EMTs were able to assess the situation.
Watch the video above to see Tebow jump into action.
