At age 20, with three wins already under the Zuffa banner, McDonald is quickly emerging as one of the UFC's brightest rising prospects. Nicknamed "Mayday," the California native is a brown belt in Brazilian jiu-jistu and has finished all but two of his professional victories, including a second-round knockout of former WEC champion Cole Escovedo. He last fought in May at UFC 130, where he edged out a narrow split decision win over Chris Cariaso for his second straight win inside the Octagon.
Meanwhile, Eduardo returns after a loss to Raphael Assuncao at UFC 134 that snapped an eleven-fight win streak stretching back to 2008. The 33-year-old Brazilian trains at Nova Uniao alongside UFC featherweight king Jose Aldo, and has finished nineteen of his twenty-five professional victories.
UFC 139 is scheduled for November 19th at the HP Pavilion in San Jose, California. Highlighting the card is a light heavyweight title eliminator between Dan Henderson and Mauricio "Shogun" Rua, and a middleweight contest between Wanderlei Silva and Cung Le.
