The Ralph C. Wilson Jr. Foundation is donating $500,000 to the Downtown Boxing Gym to support its “books before boxing” program for students and build an apprenticeship program.

The two-year grant is the largest the Detroit nonprofit has received to date, and it will be put toward its goal of serving 250 students through the free afterschool academic and athletic program by 2020, according to a news release.

Funds will be used to hire additional full-time staff and develop the next generation of boxing gym leaders.
