UFC president Dana White has long been pointing to June 13 as the target for the fight, and UFC officials finally made the official announcement on Monday.
After coaching the inaugural season of The Ultimate Fighter: Latin America, Velasquez and Werdum were scheduled to fight at UFC 180 in the same venue, but a knee injury forced Velasquez out of the bout. Werdum instead faced Mark Hunt for the interim heavyweight title and won by second-round knockout.
Having battled various injuries prior to recent troubles with his knee, Velasques hsn’t fought since October of 2013.
UFC 188 will be the second event the Las Vegas-based fight promotion has held in Mexico’s capital city.
