A 10-year-old girl who gave Kansas City Chiefs quarterback Patrick Mahomes a bracelet, which he wore to every game, has lost her battle with a brain tumor. 

Whitney Wells confirmed the sad news Monday on the Facebook page Fight for Whitney.

Whitney met Mahomes at Chiefs training camp over the summer. WDAF reports she gave the NFL MVP and tight end Travis Kelce special bracelets with her name and her mantra: "You Got This." Mahomes wore it in every game this season. 

Whitney was diagnosed with a rare brain tumor in the spring. The Chiefs heard about her diagnosis and invited the family to spend a day with them in St. Joseph. 

The Kansas City Fox station reports services will be held at 1 p.m. on Thursday, January 2 at Our Lady of Guadalupe. The burial will follow at Memorial Park.

In lieu of flowers, the family is asking that you make donations to the Whitney Kate Wells Memorial Foundation, the details of which have yet to be released.
