Aljamain Sterling isn't happy with UFC president Dana White.
The bantamweight contender expressed frustration in a series of tweets Sunday after White said he wasn't sure whether newly crowned champion Petr Yan would defend his title against Sterling or someone else.
Yan beat Jose Aldo via fifth-round TKO to win the vacant belt at UFC 251 in Abu Dhabi, United Arab Emirates on Saturday.
After Sterling defeated Cory Sandhagen in June, White said "Funk Master" was next in line to fight the winner of Saturday's title bout. Sterling is riding a five-fight winning streak, and his UFC 250 matchup against Sandhagen was widely viewed as a No. 1 contender clash.
White has said many times that he doesn't book new fights on the same night of a card. In response Saturday night to a question about the chances of Sterling getting the next title shot, White said he's only thinking about next Wednesday's event.
However, White said later in the postfight press conference that welterweight champion Kamaru Usman's next opponent will be Gilbert Burns. To Sterling, the No. 2-ranked bantamweight, White's comments seemed contradictory.
