The former two-division KSW titleholder was the last man to defeat current UFC Middleweight Champion Dricus du Plessis in their rematch in 2018, and in 2022 the 30-year-old arrived in ONE Championship as one of the most coveted free agents in MMA.
Soldić's promotional debut ended in disappointment when his fight with Murad Ramazanov was declared a No Contest due to an accidental groin strike, and the following year the Croatian suffered an upset-loss to Zebastian Kadestam at ONE Fight Night 10.
"Robocop" took nearly two years off after being stopped by Kadestam, and Soldić was given another high-profile spot for his return when he was matched up with Dagi Arslanaliev at ONE 171: Qatar.

Arslanaliev came out aggressively and seemed to surprise Soldić a bit with his striking-heavy approach, but eventually the former KSW star timed his left hand perfectly and slept Arslanaliev with a jaw-dropping knockout.
