Kaimana Nacua Sr. (born March 3, 1995) was a professional safety who carved out a journeyman career in the NFL and UFL after a standout college tenure at BYU, where he set a school record with 14 career interceptions. Despite going undrafted in 2017, he signed with the Cleveland Browns and made his NFL debut that season, later bouncing between the Ravens, Panthers, Colts, 49ers, and Jets over the next several years. In 2023, he joined the Michigan Panthers of the UFL, earning a spot on the 2024 All-UFL team and eventually playing alongside his younger brother, Samson Nacua. After being selected by the DC Defenders in the 2026 UFL Draft, he rejected the contract and announced his retirement, ending a career defined by persistence and versatility. His journey also included a notable on-field altercation during the 2014 Miami Beach Bowl, a moment that highlighted his intense competitive nature.
