Bantamweights Michael McDonald and John Lineker will headline UFC Fight Night 91.
Michael Chiesa and Tony Ferguson were expected to meet in the headlining bout of the card but the matchup fell apart when Chiesa ruptured a disc in his lower back and was forced to pull out of the fight. Ferguson will remain on the card and will face UFC newcomer Landon Vannata, an undefeated Jackson-Winklejohn fighter who accepted the bout on just over two-weeks notice.
After a two-year hiatus due to multiple hand injuries, Michael McDonald (17-3) made his return to competition last January against Masanori Kanehara and won via rear-naked-choke in the second round earning himself a post-fight bonus. Before being sidelined from the sport, McDonald had strung together an eight-fight win streak and challenged Renan Barao for the interim bantamweight title, losing via submission in the fourth round.
Lineker (27-7) has won four straight bouts with two stoppages. After missing weight four times at flyweight, Lineker was forced to move back up to bantamweight where he faced Francisco Rivera and won via first-round submission in what was named the Fight of the Night. In his last bout, he beat Rob Font via unanimous decision at UFC 198 in Curitiba, Brazil.
UFC Fight Night 91 is set to take place at the Denny Sanford Premier Center in Sioux Falls, South Dakota on July 13.
