Oklahoma and Oklahoma State fans took a needle in the arm for a great cause.
The Oklahoma Blood Institute hosted the Bedlam Blood Drive today at the Tulsa Community College.
Donors got a free T-shirt from their favorite Oklahoma team, and also got a chance to win a pair of tickets to this season's Bedlam football game.
Donors also got a chance to give to local children by trading the T-shirt for a monetary donation to St. Francis.
Organizers say summer is usually a time of great time of need for the OBI.
