Tony Ferguson will welcome Landon Vannata to the Octagon on July 13 at UFC Fight Night in Sioux Falls.
Promotion officials announced the new matchup on Tuesday. Vannata replaces Michael Chiesa, who was forced to withdraw from the lightweight bout after injuring his back in training.
Ferguson-Vannata will serve as the card’s co-main event, while a bantamweight clash pitting John Lineker against Michael McDonald has been elevated to headlining status. The event takes place at Denny Sanford Premier Center and airs on Fox Sports 1.
