The scheduled welterweight clash between Andrew Todhunter and Albert Tumenov at UFC 188 has been canceled after Todhunter was declared medically unable to compete.
The Las Vegas-based promotion announced the cancellation on Thursday night. UFC 188 takes place at Mexico City Arena in Mexico City on Saturday night and is headlined by a heavyweight title tilt between Cain Velasquez and Fabricio Werdum.
According to a report from MMAFighting.com, Todhunter passed out while trying to make weight. Todhunter was a short-notice replacement for Hector Urbina, who withdrew from the matchup with Tumenov due to injury.
