OKLAHOMA CITY (KFOR) – Oklahomans can cheer on the Oklahoma City Thunder while saving lives.

Oklahomans who donate blood during the annual Oklahoma City Thunder Holiday Blood Drive will get a free, limited-edition, long-sleeved Thunder t-shirt and a voucher for a ticket to an upcoming Oklahoma City Thunder game.
