Watch: Spurs guard Jonathan Simmons throws down massive dunk

San Antonio Spurs guard Jonathan Simmons threw down a big dunk in Sunday's Summer League game against the Milwaukee Bucks.

For the second day in a row, San Antonio Spurs guard Jonathan Simmons threw down a big dunk in Summer League action. 

After dunking over New York Knicks forward Thanasis Antetokounmpoin Saturday’s game, Simmons had another massive dunk against Michael Eric of the Milwaukee Bucks. 

Simmons used a screen to drive to the hoop and throw down a one-handed jam on Eric.

Simmons signed a two-year, minimum contract with the Spurs earlier this week after spending the last two seasons with San Antonio’s D-League team. The deal’s first year is fully guaranteed.
