Ray Nitschke Field is one of the two outdoor practice facilities of the Green Bay Packers (the other is Clarke Hinkle Field). These fields, together with the Don Hutson Center, comprise the team's training complex. The field is named for Ray Nitschke, who played for the Packers from 1958 to 1972 and whose number 66 was retired by the team. Nitschke is a member of both the Pro Football and Packers Hall of Fames.
