Montana native Jackson Thiebes played in Major League Rugby between 2020-2021, and again between 2024-2025. He represented the New England Free Jacks for his entire MLR career.

The Oregon-born lock attended the University of Montana between 2013-2017, excelling at both gridiron Football and Rugby. He is a member of Mystic River Rugby Club in New England and represented the New England Free Jacks during their exhibition season in 2019. He stuck with the Free Jacks for their inaugural MLR season in 2020, earning 3 appearances (all starts) through the first 5 games before the season was cancelled due to the COVID-19 pandemic. When the league returned Thiebes started all 16 of the Free Jacks’ games during the regular season as they fell short of a playoff spot in 2021, and was signed through the 2022 season but opted to step away from the game to focus on his career outside of rugby. He finished T-8th in MLR for tackles completed during the 2021 season, tying with Rugby ATL’s Matt Heaton on 184.

On 20th December 2023, the New England Free Jacks announced the return of Jackson Thiebes for the 2024 MLR season, where he served as a depth player earning 3 starts and 8 further appearances, helping the Free Jacks to the 2024 playoffs where they lifted their second of back-to-back MLR Shields, Thiebes’ first. On October 29th, 2024, the Free Jacks announced the return of Thiebes for the 2025 season.
