A pair of lightweights will step into the octagon at UFC 172 as Danny Castillo does battle against Isaac Vallie-Flagg. Castillo has won two of his last three under the UFC banner, with that lone loss coming to Edson Barboza at UFC On Fox IX. Vallie-Flagg will be looking to rebound from his first UFC defeat, which came to Elias Silverio at UFC Fight Night 35. UFC 172 takes place on April 26th from the Baltimore Arena in Baltimore, Maryland with Jon Jones and Glover Teixeira headlining.
