Celtics fans chanted "We want Tacko!" throughout Sunday's preseason game vs. the Cavaliers, and they got their wish in the fourth quarter.

Tacko Fall immediately made his presence felt with a dunk, and the TD Garden crowd promptly went bonkers.

Watch below:

TackoMania continues.

Celtics fans can expect to see plenty more of Tacko for the foreseeable future as the UCF product signed a two-way contract earlier on Sunday. Fall will spend most of the season with the G-League's Maine Red Claws and can spend up to 45 days on the NBA roster.

The C's went on to dominate the Cavs, 118-72.
