As of September 15, 2026, he is listed on Dallas’ 2026 roster as No. 66 and has moved into a larger role on the offensive interior, including a starting assignment at left guard in place of Tyler Smith. Bass originally joined the Cowboys as an undrafted free agent after the 2023 NFL Draft and has remained with the organization since signing on May 12, 2023.

Bass began his college career at Butte College, where he played for two seasons before transferring to Oregon. With the Ducks, he developed experience at multiple offensive-line positions and earned first-team All-Pac-12 recognition in each of his final two seasons. Dallas valued that versatility, viewing him as a lineman capable of moving between tackle and guard while adjusting to different protection and blocking responsibilities.

The Cowboys list Bass at 6 feet 5 inches and 320 pounds, with a birth date of March 31, 1999. His professional profile is built around positional flexibility, physical play and the ability to provide dependable interior depth. His progression from junior-college football to Oregon and then to an NFL roster reflects a development path based on adaptability and continued improvement rather than draft status.
