It's official -- though we were worried he wouldn't have a role, Brad Stevens simply wouldn't have it.

Following camp, the Boston Celtics have signed undrafted rookie Tacko Fall out of the University of Central Florida.

The former AAC Defensive Player of the Year has made noise as an NBA prospect for his very rare size. The 7-7 center nearly broke every measurement mark at the NBA Combine, leading several teams to pursue him as a potential addition to their Summer League rosters.

The Celtics won that hunt, and they liked what they saw. In five games of NBA Summer League action, Fall posted 7.2 points, 4.0 rebounds, and 1.2 blocks on 77% shooting in just 12.6 minutes per contest.

The Senegalese center was also effective at UCF, of course, where he averaged 11.1 points, 7.6 boards, and 2.6 blocks per game on 74.8% shooting in his senior year. His season-long production eventually would earn him a spot on the All-AAC Third Team.

With the defensively-challenged Enes Kanter set to receive a large role in Boston's rotation with the departure of Al Horford, Fall should slide in nicely as the third-string big man behind Daniel Theis.
