Former University of Arizona star and current Minnesota Timberwolf Derrick Williams has reportedly signed an endorsement deal with Under Armour.

Williams, an electrifying college player who led the Wildcats past top-seeded Duke to reach the Elite 8 in the 2011 NCAA tournament, was the number two overall pick in June’s NBA draft.

Williams is the second NBA rookie inked to a contract with Under Armour, joining the Charlotte Bobcats Kemba Walker, who announced his signing with UA earlier this month. Williams signing is the latest development in what has become an endorsement competition between Nike Basketball and Under Armour basketball to sign potential NBA future superstars.

Nike announced last week it had signed former Duke guard and Cleveland Cavaliers number one overall pick Kyrie Irving to a shoe deal.
