University of Central Florida's big man Tacko Fall didn't find any takers in the 2019 NBA Draft—and he could be making teams regret that decision very soon.

Fall, a 23-year-old center who played four years in the AAC at UCF, signed a deal with the Boston Celtics as an undrafted player to participate in the NBA's Summer League in Las Vegas, Nevada.

The Senegalese product is already turning heads in Vegas, however, as Celtics head coach Brad Stevens told Boston Sports Journal's Brian Robb:

“He has the whole place buzzing and it doesn’t affect who he is. I admire him.”

In two games in Summer League, the ginormous Tall, at 7-foot-6, has only missed one field goal attempt, shooting 8-for-9 from the floor in 22 total minutes and scoring 18 points.

At UCF, Fall averaged 10.1 points, 7.7 rebounds, and 2.4 blocks in 23 minutes per game and 115 total collegiate appearances. He shot an immaculate 74% from the field and a ghastly 43.2% from the free throw line.

It's unclear if Fall will have any spot on Boston's roster come autumn, but he's working his way there.

The Celtics lost All-Star big man Al Horford to Atlantic Division rivals Philadelphia 76ers in free agency this summer.

They also signed Enes Kanter, formerly of the New York Knicks and Western Conference Finals runner-ups Portland Trail Blazers, and traded center Aron Baynes to the Phoenix Suns.
