Signing Details and Immediate Context
Former Nebraska forward Rienk Mast signed an Exhibit 10 contract with the Indiana Pacers on Thursday, following the conclusion of the 2026 NBA Draft. The one-year, non-guaranteed agreement gives Mast a chance to earn a roster spot during the Pacers’ Summer League and training camp. Indiana entered the 2025-26 season as the reigning Eastern Conference champion.
Nebraska Career Overview
Mast redshirted the 2019-20 season after a knee injury, then played three full seasons for the Cornhuskers. He totaled 1,894 points, 1,094 rebounds and 351 assists in 154 games, including a triple-double against FIU on Nov. 8, 2025. As a senior in 2025-26 he started 34 games, averaged 13.3 points, 5.8 rebounds and 3.1 assists, and helped Nebraska achieve a program-best 28-7 record, its first NCAA tournament victory, and its inaugural Sweet 16 appearance.
Data & Statistics
- Career totals: 1,894 points, 1,094 rebounds, 351 assists (154 games)
- Senior season averages: 13.3 pts, 5.8 reb, 3.1 ast per game

Why It Matters / Impact
Mast’s signing highlights the growing Nebraska NBA pipeline under head coach Fred Hoiberg. The program now counts 15 former players who have reached the NBA, including two drafted during Hoiberg’s tenure (Dalano Banton, 2021; Bryce McGowens, 2022). Mast’s decision to return for his senior year and his subsequent professional opportunity provide a tangible recruiting narrative for future prospects.
Official Statements & Responses
Nebraska Athletics announced that “The Dunking Dutchman” had agreed to an Exhibit 10 deal with the Pacers, describing the contract as a one-year, non-guaranteed, minimum-salary agreement that allows undrafted players to compete in training camp and Summer League. The Pacers’ front office confirmed Mast will be evaluated during Summer League and that the organization is interested in his versatile scoring and perimeter shooting.
Criticism & Opposition
Analysts note lingering health and durability concerns stemming from Mast’s May 2024 knee injury, which caused him to miss the entire 2024-25 season. While his senior production was strong, questions remain about his ability to sustain NBA-level minutes and adapt to the physical demands of the professional game.
Conflicting Reports & Gaps
Sources uniformly describe the contract as an Exhibit 10 deal; however, some outlets refer to it as a “free-agent” or “non-guaranteed” agreement. No source provides details on the exact bonus structure or the Pacers’ timeline for converting the contract to a two-way deal, leaving those terms ambiguous.

What’s Next
Mast will join the Pacers for Summer League in July, after which his performance will be reviewed by the coaching staff. If waived during training camp, he can sign with the Pacers’ G League affiliate and remain eligible for an Exhibit 10 bonus of up to $75,000 after a 60-day stint. Successful evaluation could lead to a two-way contract for the 2026-27 NBA season.
