Perennial Ultimate Fighting Championship featherweight contender Chan Sung Jung on Saturday will square off with Dana White’s Contender Series alum Dan Ige in the UFC on ESPN 25 main event at the UFC Apex in Las Vegas. Meanwhile, Russian submission specialist Alexey Oleynik, less than a week shy of his 44th birthday, meets Sergey Spivak in the heavyweight co-headliner.
