UFC heavyweight Ben Rothwell will return to the octagon after almost three years on the sidelines when he faces ex-Bellator champ Blagoy Ivanov in March.

The fight was first reported by Bulgarian MMA site MMA.bg and confirmed by MMAjunkie with a person close to negotiations, who requested anonymity because the UFC hasn’t announced the fight and did not reveal a specific date for the matchup.

Rothwell (36-10 MMA, 6-4 UFC), 37, was last seen in the octagon in April 2016 when he was outworked by ex-champ Junior Dos Santos at UFC Fight Night 86. The loss snapped an impressive four-fight winning streak that put the IFL and Affliction veteran on the verge of a UFC title shot.

A serious knee injury subsequently ruled Rothwell out of a fight against ex-champ Fabricio Werdum at UFC 203 in September 2016. The bout was rescheduled for UFC 211 in May 2017, only to be canceled when Rothwell failed an out-of-competition drug test administered by UFC anti-doping partner U.S. Anti-Doping Agency (USADA). Rothwell later was issued a two-year suspension for an “anabolic androgenic steroid of exogenous origin.”

Rothwell submitted paperwork from his doctor showing he’d undergone testosterone replacement therapy at the direction of his doctor; in 2013, he was issued a nine-month suspension by the UFC for elevated levels of testosterone despite a therapeutic-use exemption for a fight at UFC 164.

Rothwell said his doctors prescribed TRT to deal with a testosterone deficiency caused by a car wreck.

In Dos Santos, Ivanov (16-2-1 MMA, 0-1 UFC) shares a most recent opponent and outcome with Rothwell. The ex-Bellator champ took on Dos Santos at UFC Fight Night 133 in July and was dominated en-route to a unanimous decision loss. The setback snapped a five-fight winning streak that included a title run in the now-defunct WSOF.
