Travis Kelce may have been struck by Cupid's arrow ... but he took a different type of hit at his Kansas City Chiefs game last night when he was slapped by his opponent!
Take a look at the clip from the Chiefs' game against the Los Angeles Chargers in São Paulo, Brazil, Friday night -- defensive tackle Teair Tart unleashed his wrath on Travis ... brutally slapping him across his face.
The wild attack came during the game's 3rd quarter after TK collided with and shoved TT during a block, which clearly PO'd Teair.
