COLORADO SPRINGS, Colo. — Joshua Farris, the 2015 U.S. bronze medallist , who has been sidelined while recovering from a concussion, has retired.

Farris, 21, won the 2013 world junior champion and appeared to be a rising star in the sport. But he fell badly while attempting a quadruple jump last July in practice.

"I am heartbroken that my competitive skating career is coming to an end before I was ready, but I plan to stay involved in the sport that has given me so much," said Farris, a native of Renton, Washington who lived in Colorado Springs. "While I focus on regaining my health, I will continue to skate, coach and choreograph. I also plan to volunteer as a figure skating official, pursue my college education and work on my music."
