@Alistairovereem been mentioning my name everywhere . I'm now open and free for you guy . Let do this at #ufc215 — Francis NGannou (@francis_ngannou) August 19, 2017

Now that Junior dos Santos is sidelined due to a potential anti-doping violation, Francis Ngannou needs an opponent at UFC 215 . The surging Frenchman already has someone in mind.“[ Alistair Overeem ] been mentioning my name everywhere,” Ngannou wrote on Twitter. “I’m now open and free for you guy. Let’s do this at [UFC 215].”UFC 215 is three weeks away, and while the promotion is searching for a replacement foe for Ngannou, it is unclear if Overeem would be willing to take such a high-profile bout on short notice. The Jackson-Wink MMA product last appeared at UFC 213, where he captured a majority decision against Fabricio Werdum . Overeem has won six of his last seven in the Octagon overall, with his only defeat coming in a title bout against Stipe Miocic at UFC 203.The 30-year-old Ngannou is currently riding a nine-fight winning streak. Five of those triumphs have occurred in UFC competition, with each victory ending inside of two rounds. Most recently, “The Predator” scored a first-round TKO of Andrei Arlovski at UFC on Fox 23.
