After adding ten newcomers to the 2025-26 roster, head coach Eric Konkol has announced the 11th member of the class with the signing of Leon Sifferlin. The guard from France joins the Golden Hurricane for the upcoming season.

"We are happy that Leon has joined our program," remarked head coach Eric Konkol. "He has great size and skill for a guard and brings tremendous experience from the international stage. He is a gifted passer and can also stretch the defense with his perimeter shooting. We like his feel on the court, the effort he plays with, and how hard he works on his game."

He brings a wealth of international experience to Tulsa, having represented his country at multiple levels. Sifferlin was a member of the French U19 National Team in 2025, played for France at the FIBA U18 EuroBasket, and made his international debut with the France U16 squad at the 2022 European Championship.

The shooting guard most recently competed for JL Bourg en Bresse in France's Betclic ELITE ProA League. Sifferlin also won the French U21 Championship where he averaged 14.7 points, 5.6 assists, 3.8 rebounds and 2.1 steals per game in his career in France.

Earlier this summer, TU welcomed 10 new players to the squad this season with the addition of eight transfers, a JUCO product, and two freshmen. Miles Barnstable, Ade Popoola, Myles Rigsby, Tylen Riley, Doryan Onwuchekwa, Terrance Ford Jr., David Green, Carter Benton, and Romad Dean have all transferred in and joined Jaylen Lawal and KJ Martin Jr. to the class. College basketball analytics expert Evan Miyakawa has ranked Tulsa's eight-player transfer class as the second-best this offseason among American Conference teams.

The Golden Hurricane returns three from last season's squad, including Ian Smikle, who started in 28 games. Smikle was named to the 2024-25 American All-Freshman team and finished third on Tulsa's all-time freshman rebounding list with 183.
