CSU athletic director Joe Parker announced the news Friday, a day after the school's governing board approved a motion regarding stadium naming rights but refused to release details.
The field at the existing Hughes Stadium is also named for the former football coach who led the Rams to six conference titles and nine bowl games in 15 seasons. The school still has the ability to sell the naming rights to the stadium itself separately.
The donation for the field's naming rights exceeds the amount the school anticipated getting for the naming rights for both the field and the stadium.
The stadium is expected to be ready for the 2017 football season.
