For what noble cause have Dale Jr., Danica Patrick teamed up?
When Danica Patrick drove in the Nationwide Series for JR Motorsports from 2010-2012, Dale Earnhardt Jr. was her boss.
Since 2013, when Patrick joined the Sprint Cup Series full time with Stewart-Haas Racing, the two ultra-popular drivers have been competitors.
The two remain friends, however, and that friendship was on display this week when Patrick sent Earnhardt Jr. a note on Twitter.
The subject matter?
Patrick wanted to donate her driving gloves from the recent Bank of America 500 at Charlotte Motor Speedway to the Dale Earnhardt Jr. Foundation to raise funds for the NASCAR Breast Cancer Foundation.
In honor of Breast Cancer Awareness Month, Earnhardt Jr.'s familiar skeleton-hand gloves have taken on a pink hue for every race in October, and will do so again this weekend at Martinsville Speedway.
The proceeds from all the gloves, which are being auctioned off on eBay through the Dale Jr. Foundation, will benefit breast cancer research through a breast cancer organization of Earnhardt and girlfriend Amy Reimann's choice.
Throughout September, National Ovarian Cancer Awareness Month, Earnhardt Jr.'s skeleton-hand gloves were colored teal to raise awareness and money for ovarian cancer.
Each pair of teal gloves was auctioned through the Dale Jr. Foundation to benefit a charity hand-picked by Sherry Pollex, the girlfriend of friend and fellow driver Martin Truex Jr.
Pollex was diagnosed with ovarian cancer in August.
As for Danica's proposed donation to the Dale Jr. Foundation, Earnhardt gladly accepted.
Hey @DaleJr I love how you're auctioning off your gloves! I want to donate my pink gloves from Charlotte to @tdjf to raise money for @NBCF.
