Rafael Nadal has accepted, via Twitter, a challenge proposed by an 11-year-old Lebanese by the name of Marc Krajekian, similar to the trendy 2014 “Ice bucket challenge”, dubbed the “Volleying challenge”. He was nominated alongside the boy’s hero, Roger Federer and the NBA star Michael Jordan.

It aims at showing support and solidarity with cancer patients, among whom Marc was.
