Each year, in advance of the football matchup between Kentucky and Tennessee, the Kentucky Blood Center invites UK fans to participate in the Big Blue Crush, a blood battle between Wildcat and Volunteer fans. In 2010, Kentucky won the competition for the first time since 2002 and is looking to keep the title on the right side of the border for the second straight year. Last year, Kentuckians donated a record 3,503 pints of blood during the weeklong battle.The 24th annual Big Blue Crush began today and continues all this week.  It’s a friendly competition between UK and UT fans that also helps ensure a strong blood supply throughout the holiday season.As if beating Tennessee and contributing to a worthy cause weren’t enough motivation to participate, the Kentucky Blood Center is also giving away plenty of great prizes. All donors will receive a Big Blue Crush t-shirt and coupon for a free McCafe Beverage from McDonald’s. Each day, one winner of a $200 gas card will be chosen, while Monday and Tuesday donors will be entered to win a pair of tickets to this year’s UK-Tennessee game at Commonwealth Stadium. The grand prize is an NCAA game package to be chosen from among all donors.Visit the Kentucky Blood Center’s website to make an appointment to donate today.Also, here’s a video put together by the Kentucky Blood Center in preparation for the drive.
