The coronavirus pandemic has temporarily (we hope) changed the face of sport as we know it, with cancellations becoming somewhat of a daily occurrence.
However, with less game-time, it gives the otherwise occupied professionals a chance to try something new.

The world no4 has previously donated one million Swiss Francs (roughly £840,000) to vulnerable families affected by the coronavirus crisis.
He's not the only one getting creative, however. Below is a look at what some other sporting figures got up to on Monday....
Van Der Sar gets creative with his clothing choices for video conferences
Cristiano Ronaldo enjoys some quality family time
Sam Ward's Isolation Olympics continues
Ben Stokes continues Bring Sally Up challenge
