Just because the 2025 NBA draft is over, doesn’t mean teams stop ringing the phones. As soon as the last pick is announced, a whole class of undrafted free agents hope to get signed by an NBA squad with summer league weeks away.

The Oklahoma City Thunder drafted Georgetown’s Thomas Sorber with the No. 15 pick and Northwestern’s Brooks Barnhizer with the No. 44 pick. Now, they added somebody from undrafted free agency.

The Thunder have reportedly signed California’s Mady Sissoko to a deal, per Draft Express’ Jon Chepkevich. He played in five college seasons from 2020-25. He spent his first four years at Michigan State before transferring to California.

Sissoko averaged 8.3 points on 65.3% shooting, 8.2 rebounds and 0.4 assists. He shot 69.6% on free throws. He also tallied 1.1 blocks. The 24-year-old is a 6-foot-9, 250-pound center.

Sissoko will get a chance to play for the Thunder on their summer league squad. If he impresses enough, he could get added to their G League’s OKC Blue roster. The Thunder’s summer league schedule can be viewed here.
