Robinson's No. 89 jersey will be retired during a halftime ceremony.
According to Moorestown athletic director Neil Rosa, the football jersey will be the first ever retired by the school.
In addition, Robinson, who lives in Akron, Ohio, is expected to speak to a school assembly that afternoon and address the Moorestown team before the game.
The school will sell commemorative programs of the event signed by Robinson.
The halftime ceremony will include a proclamation by the Moorestown Township Council.
Robinson is a 1959 Moorestown graduate who was a star football, basketball, and track athlete during his high school career.
"He also was a straight-A student and member of the dean's list at Penn State and earned his engineering degree," Gray said.
Robinson played on three undefeated teams at Moorestown: the 1958 and 1959 basketball teams (which went a combined 44-0) and the 1957 football team (9-0).
Robinson played football at Penn State and was a star linebacker for the Green Bay Packers during that franchise's historic championship run under coach Vince Lombardi in the 1960s.
Robinson was a member of the Green Bay teams that won the first two Super Bowls, and he was named to the NFL's all-decade team for the 1960s.
Robinson was inducted into the Pro Football Hall of Fame in August.
In conjunction with the Sept. 12 event, a group that includes Robinson's niece, Rayette Smith - whose son Tyreek is a standout two-way lineman for this year's Moorestown team - has commissioned an artist to create a bust of Robinson for the trophy case.
Gray said that John Giannotti of Woodbridge, N.J., has been commissioned to create the bust. Giannotti, former chairman of the fine-arts department at Rutgers-Camden and creator of the one-ton dinosaur sculpture in downtown Haddonfield, is going to unveil a rendering of the bust at the Sept. 12 game, Gray said.
The group estimates the cost of the project to be $9,000. About $3,600 had been raised as of Tuesday.
