Jackson spent his high school days playing rugby and football.
He was recruited to Lewis and Clark as a tight-end, before transferring to the University of Montana where he became a third-team all-conference offensive tackle at over 300 lbs.
Thiebes signed for the New England Free Jacks having done a few weeks with Rugby United New York on loan.
He enjoyed his best season in 2021, starting all 16 games for the Free Jacks and playing 93% of all possible minutes. His form drew the attention of Eagles selectors who noted an increasingly influential carrying game to go with strong set piece attributes and a high work rate.
In November 2021, he announced his retirement from rugby at the age of 27 to pursue a career outside of the sport
