DENVER (CBS4) – Broncos linebacker Shane Ray is hoping Broncos fans will join him in an effort to help the American Diabetes Association.

Ray has teamed up with the company Cheerful Giving to present a contest that gives people who donate to the association a chance at winning tickets to the Broncos final game of the regular season.

To enter, between now and Dec. 18 fans can go to cheerfulgiving.com/champion/shaneray or download the Cheerful Giving app on the App Store or on Google Play. Anyone who donates $25 (or more) to the American Diabetes Association is automatically entered into the “The Ultimate Game Day Experience” contest.

The winner gets:

– 2 premium seats provided by TicketCity for the Broncos-Raiders game on Jan. 1 in Denver
