What started as a team gesture has turned into a call for all Indianapolis Colts' fans - and cheerleaders - to show their support for cancer research.
It started with more than 25 Colts players shaving their heads to show support for head coach Chuck Pagano, who's currently battling leukemia.
Now, the show of support has spread to the spirit side of the team.
This week, Colts mascot Blue sent out a challenge to all Colts cheerleaders via Twitter that if he could raise $10,000 for leukemia research by the Colts vs. Bills game on Nov. 25, one cheerleader would have to shave her head.
Blue is now asking fans to make a donation to the CHUCKSTRONG fund on the Colts website.
Money raised through the challenge will benefit leukemia research at the IU Health Simon Cancer Center in Indianapolis.
