Per Dave Biddle, Urban Meyer has reached out to the Harley family, and has been granted permission to issue the #47 to Hilliard.

The #47 was originally retired in 2004, in the honor of Chic Harley, who was a three-time All-American for the Buckeyes (1916, ’17, ’19) and helped put Ohio State football on the national map. In fact, Ohio Stadium, which opened in 1922, is known as the “House That Harley Built.”
