Things got heated on Monday night between the Boston Celtics and the Milwaukee Bucks. Al Horford turned back the clock for a vintage performance and apparently, Giannis Antetokounmpo's antics may have had a lot to do with the Celtics veteran's unexpected explosion on the offensive end.

At one point in the game, Giannis threw the hammer down all over Horford. For good measure, the Bucks superstar stared down Horford after the poster dunk. The referees even slapped Antetokounmpo with a technical foul for taunting:

Horford was clearly fired up by Giannis' actions and he made sure to get him back later in the game. The Celtics big man got his revenge with a massive poster dunk on Antetokounmpo. To add insult to injury, Horford even clocked Giannis with an elbow after the dunk and it sent the former back-to-back MVP to the floor.

Horford was assessed with a technical foul for his extra motion but I'm pretty sure the Celtics vet won't mind that one bit.

Boston came away with a huge Game 4 victory, 116-108, to tie the series at 2-2. Game 5 is scheduled for Wednesday night in Boston.
