Jon Chepkevich reports that Mady Sissoko has a Summer League contract with the Oklahoma City Thunder.

Cal’s Mady Sissoko will join the Oklahoma City Thunder for NBA Summer League, I’m told.

The Malian big man boasts a 6’9”, 250 pound frame with a 7’3” wingspan and 9’2” standing reach.

8.3 PTS, 8.2 REB, 1.1 BLK, 68.8 TS% this season.

The Thunder will play 3 games in Salt Lake City on July 5-8 (schedule) and at least 5 games in Las Vegas on July 10-20 (schedule).

Summer League rosters have not been announced yet, but so far we know that, in addition to Sissoko, the following undrafted rookies have made deals with the Thunder:

Zack Austin (Pittsburgh)
Erik Reynolds II (Saint Joseph's)
Payton Sandfort (Iowa)

And the OKC draft picks, if healthy, will also play on the Summer League team:

Thomas Sorber (Georgetown)
Brooks Barnhizer (Northwestern)

Mady and Wilkerson were my fav players on last year's team

Coming to Cal was the best thing he could have done for his career, as he steadily improved, and Coach Madsen was the perfect coach for him
