New England Patriots star Rob Gronkowski was one of the hundreds of people who participated in the One Mission Buzz Off Sunday at Gillette Stadium, which raised money to fund pediatric cancer research and services for children with cancer. Patriots lineman Nate Solder, who is a cancer survivor and has a son who was diagnosed with cancer in 2015, also attended the event and helped shave the heads of participants.

Had a great time this morning at the kids cancer buzz off. It's an honor to always represent this event. So many great people and kids helping out to raise $ for a great cause. I love my fresh summer look!
