Alistair Overeem has a new opponent.
Jairzinho Rozenstruik will replace Walt Harris in the main event of UFC Washington on Dec. 7, president Dana White told ESPN's Brett Okamoto.
Harris withdrew from the event as the search continues for his missing 19-year-old stepdaughter.
Rozenstruik is freshly removed from a 29-second knockout of Andrei Arlovski at UFC 244 on Saturday.
Rozenstruik owns a spotless 9-0 professional record, but Overeem represents a steep step up. The No. 6-ranked heavyweight owns a career mark of 45-17-1 and scored first-round TKO victories in his last two fights.
