In September 2012, Rippon announced a coaching change, moving to train with Rafael Arutyunyan in Lake Arrowhead, California. At the 2012 Cup of China, Rippon collided with China's Song Nan – who sustained a concussion and withdrew – a minute into the final warm up before the free skate. Rippon said, "I kind of turned around to go into a jump and I think when Nan Song and I saw each other we both tried to avoid each other, but we went in the same way and we went head first into each other." Rippon finished 4th at the event and 8th at the 2012 NHK Trophy. At the 2013 U.S. Championships, he landed three triple Axels and finished 5th. He was assigned to the 2013 Four Continents but withdrew after sustaining an ankle injury on February 2, 2013.
