Flyweight Ian McCall has been forced to withdraw from next month’s UFC Fight Night 37 event, and promotion officials are currently seeking a replacement opponent for Brad Pickett.

UFC President Dana White revealed the change at a media luncheon in Las Vegas, which MMAjunkie attended.

Featuring a light heavyweight matchup between Alexander Gustafsson and undefeated striking specialist Jimi Manuwa, UFC Fight Night 37 takes place March 8 at London’s O2 Arena. The entire 10-fight event streams on UFC Fight Pass in the U.S.

Pickett, who’s won four “Fight of the Night” bonuses in six UFC fights, is currently ranked No. 5 in the USA TODAY Sports/MMAjunkie MMA bantamweight rankings. However, with losses to contenders such as Michael McDonald and Eddie Wineland during his current 3-2 run, the 35-year-old Englishman is looking to make his flyweight debut.

Meanwhile, the 29-year-old McCall recently halted a three-fight winless streak (a draw and loss to Demetrious Johnson, as well as a defeat to Joseph Benavidez) with a unanimous-decision win over Iliarde Santos in August. “Uncle Creepy” picked up a “Fight of the Night” bonus for the effort. However, he’s now pulled out of two consecutive bouts after being forced to withdraw from a planned matchup with Scott Jorgensen that was slated to take place at December’s UFC on FOX 9 event.
