Rutgers football player Eric LeGrand was left unable to move from the neck down after being injured making a tackle in a game against Army on Saturday.
The helmets of high school football players around New Jersey will feature the number of the Rutgers University tackle who was paralyzed.
Riddell is distributing the oval No. 52 decals in scarlet numerals without charge to approximately 150 high schools, as well as Kean and William Paterson universities.
The concept started at Eric LeGrand's alma mater, Colonia High School.
Riddell will send "memo invoices'' to schools if they want to make donations that will go toward a fund for LeGrand.
The junior remains paralyzed from the neck down after he made a tackle on a kickoff return against Army last Saturday.
