Anyone who donates will be entered to win a pair of tickets to a regular season game. Fifty people will win.
All donors will also be treated to tours of the field and the game-day locker room.
The drive takes place from 9 a.m. to 3 p.m. at the stadium. Donors can enter at Gate Two.
Teens 16 years of age and under can donate with the consent of a parent or guardian.
