Ferris won two bronze medals at the 1968 Summer Olympics in Mexico City: one in the men's 200-meter individual medley and one in the men's 200-meter butterfly. His third-place finish in the 200-meter individual medley completed an American sweep of the event, with Charlie Hickcox taking first and Greg Buckingham taking second.
