Damar Hamlin got his first-ever interception against the Jaguars on Monday night -- and considering he nearly lost his life the last time he played on a Monday ... the moment was super sweet.
The scene unfolded late in the second quarter of Buffalo's 47-10 "Monday Night Football" win over Jacksonville ... when Trevor Lawrence sailed a pass over his intended target's head on a first-and-10 throw.
The ball landed right in Hamlin's chest -- and after he secured it, he took it back some 20-or-so yards .
