As of noon Tuesday, Arizona State will be the final Adidas school in the Pac-12.
UCLA is expected to announced a record-setting deal with Under Amour and leave Adidas, which has provided apparel to the school since 1999.
Under Armour is trying to gain a foothold on the West Coast as the Maryland-based company struck a deal with Cal last month. Utah was the first Pac-12 school to sign with Under Armour when it inked a schoolwide deal in July 2011.
UCLA is the latest school to leave Adidas. Notre Dame also left the company to sign with Under Armour in 2014 in a 10-year, $90 million deal that was, at the time, the largest in history. Tennessee ditched Adidas for Nike in 2014, while Wisconsin is picked Under Armour over 3-stripe life in 2015.
Meanwhile, Arizona State signed with Adidas in 2014, leaving Nike, the dominant apparel sponsor in the Pac-12.
