Robert Crow was a plastic and reconstructive surgeon working for the Atlanta Braves in the 1970s when he invented a device that could protect players who were coming back from facial injuries. He called it a "C-Flap" after his last name and what it protected — the cheek. The device could be attached to the ear flap of the standard helmet to offer the added protection. The device did not become mainstream until decades later and in the meantime, players tried various things for the same purpose. For example, in 1978, the Pirates Dave Parker wore a hockey mask at the plate after he broke his cheek and jaw bones in a collision at home plate. This lasted only one game and Parker then tried to use a helmet with an attached two-bar football facemask. He also tried a helmet with another football facemask, the Dungard 210 facemask, screwed into his helmet.
