A training injury has forced flyweight contender Ian McCall from his UFC Fight Night bout against Dustin Ortiz on August 8 in Nashville. Stepping in for "Uncle Creepy" against Tennessee's Ortiz will be Willie Gates, fresh from a first-round knockout of Darrell Montague earlier this month.

Also bit by the injury bug for the August 8 event is veteran Joe Riggs, whose return to the middleweight division will have to wait. Now facing his opponent at the Bridgestone Arena, Uriah Hall, will be Octagon newcomer Oluwale Bamgbose, whose perfect record has seen him win all five pro bouts by knockout.

The UFC Fight Night card, which is headlined by the light heavyweight bout between Ovince Saint Preux and Glover Teixeira, will be televised live on FOX Sports 1.
