Ian was originally scheduled to rematch against reigning champion Aljamain Sterling at the upcoming tournament, but the American withdrew due to injury. In their first bout on March 6, the Russian inflicted an illegal knee, for which he was disqualified and stripped of his belt.
Prior to the loss to Sterling, the 28-year-old Ian (15-2) was on a streak of ten straight wins. The 28-year-old Sandhagen (14-3) lost his last fight by split decision to T.J. Dillashaw.
