John Orozco’s second Olympic bid ended before it could start. The Bronx-born gymnast tore the anterior cruciate ligament and meniscus in his left knee while dismounting from the horizontal bar during Olympic team training camp, U.S.A. Gymnastics announced Friday. The knee injury is the same one he suffered in October 2012 and, as a result, he will miss the 2016 Games in Rio de Janeiro.
