Shock Doctor, McDavid and Cutters, three divisions of United Sports Brands, have entered into an official partnership with USA Football. McDavid is now an official partner of USA Football while Cutters is its official glove and Shock Doctor its official mouthguard. In addition, products from the three brands will be worn by athletes selected to the U.S. National Team program during USA Football-sanctioned events. The sponsorship deal builds on a long-standing relationship with USA Football, as Shock Doctor partnered with the organization in 2010 and Cutters joined the partnership in 2012. USA Football, based in Indianapolis, trains high school and youth football coaches in the U.S. The organization is a member of the U.S. Olympic Committee, and its programs include its medically-endorsed Heads Up Football program. Nearly 70 percent of all U.S. youth leagues and more than 1,100 high schools enrolled in Heads Up Football in 2015.
