Indianapolis Colts linebacker D'Qwell Jackson has been found guilty of attacking a pizza delivery boy during an argument over a parking space last year ... TMZ Sports has learned.
As we previously reported, Jackson -- who intercepted the pass that started Deflate-gate -- was arrested in Washington D.C. back in February '15 after a pizza boy told cops the Pro Bowler punched him in the face.
Officials say the pizza boy claimed the two had been arguing over a parking spot when Jackson hit him in the face and the back of the head.
