Don Frye
In 1996, Bitetti debuted in Ultimate Fighting Championship at its event UFC 9, replacing an injured Marco Ruas in his fight against Don Frye. The match would become infamous for the amount of punishment Amaury received, as Frye stopped his early takedowns and started landing punches, knees and elbows on the Brazilian, both standing and on the ground. After a hard series of elbows to the spine and head, the referee stopped the match to declare Frye winner.
