Boston selected the Houston product 27th overall in 2026; a fact-based look at his lone college season, summer league play, prep career and USA Basketball resume.

The Boston Celtics used the 27th selection in the 2026 NBA draft on Chris Cenac Jr., a 19-year-old forward who played one season of college basketball at Houston. He reaches the NBA after a freshman year in which he stood out nationally as a young defender and rebounder.

Across 37 games with the Cougars, Cenac produced 9.5 points and 7.9 rebounds per contest on 48.5% shooting from the field. His defensive rating of 92.2 sat eighth among players nationwide, and his defensive rebounding percentage of 26.1 ranked 20th.

Listed at 6-foot-11, Cenac became the first Houston freshman to pace the team in rebounding since the 2011-12 campaign. His six double-doubles represented the fourth-best single-season figure ever recorded by a Cougars first-year player. He was also one of three Houston players chosen in 2026, alongside Kingston Flemings at No. 8 and Emanuel Sharp at No. 45 — only the second instance since the common draft began in 1966 that the school has had three selections in a single draft.

Cenac appeared in four summer-league games for Boston, posting averages of 10.5 points, eight rebounds, 2.8 blocks and one assist. Two double-doubles came in that span, among them a 14-point, 10-rebound effort on July 10. The Celtics coveted him in the first round for his glass work, his defense and his motor, and the franchise has voiced enthusiasm about his arrival and his debut on the floor.

On uniform numbers, Cenac previously wore 12 at Riverside Academy, 0 at Link Academy and 5 during his Houston season. With so many digits already retired in Boston, his options were narrow, and he returned to No. 12. Speaking at a community event on June 30, in comments carried by Celtics on CLNS, he confirmed the choice and added, "I think it was the best number that was available, honestly."

Cenac's prep career also included a stint at the Isidore Newman School in Louisiana, where he played for Randy Livingston, a former NBA guard whose career spanned 11 seasons. He attended the New Orleans school at the same time as Texas quarterback Arch Manning and helped the program secure a third consecutive state championship.

In 2024, Cenac collected MVP honors at the NBPA Top 100 Camp, staged at the ESPN Wide World of Sports Complex inside the Walt Disney World Resort near Orlando, Florida. He topped all participants with 11.4 rebounds per game and placed third with 1.6 blocks. He was additionally named the MVP of Puma's PRO16 league.

Rated a five-star prospect, Cenac sat sixth in the national rankings for the class of 2025 and first among centers, which made him the most highly ranked recruit Houston has signed in the modern era. He committed to the Cougars over a finalist group that included Auburn, Baylor, Kentucky and Tennessee, among other programs.

Cenac earned a gold medal with USA Basketball at the 2024 FIBA U17 World Cup, sharing the roster with AJ Dybantsa, Cameron Boozer and Koa Peat. Over seven games he contributed 8.9 points, 5.4 rebounds, 1.1 assists and one steal per outing.
