Maness was scheduled to take on Maksum in a flyweight bout on Feb. 3 at the UFC Apex in Las Vegas. Johnson has reportedly agreed to step up on short notice, according to MMAjunkie.com. The matchup has not been officially announced by the promotion.
Johnson has lost three straight within the Las Vegas-based promotion, including a unanimous decision defeat against Rafael Estevam in his most recent appearance at UFC Fight Night 232 this past November. He is 2-4 in UFC competition overall.
A former Octagon Promotion flyweight champ, Maksum notched a split decision win over flyweight veteran Tyson Nam in his promotional debut at UFC on ESPN 49 in July.
UFC Fight Night 235 is headlined by a middleweight meeting between ranked Roman Dolidze and ranked Nassourdine Imavov. Meanwhile, the co-main event will feature a lightweight showdown between Drew Dober and the returning Renato Carneiro, who has been out of action for more than a year due to a knee injury.
