The Indianapolis colts mascot, Bue, shaved the heads of two Colts cheerleaders to raise $10,000 dollars for Leukemia research and in support of Colts coach Chuck Pagano.
They're sacraficing their locks to raise money for cancer research.
Plenty of people have done it for friends and relatives and about thirty Colts did it for Coach Pagano.
Mr Pagano was diagnosed with Leukemia back in September of this year.
