Laver Cup to be played on a black court

The Laver Cup begins on Friday and already promises to be one-of-a-kind. The team exhibition boasts incredible talent, led by Rafael Nadal and Roger Federer, and includes legendary captains, John McEnroe and Bjorn Borg. The whole thing is meant to honor one of the biggest legends in the sport, Rod Laver.

And still, there's more to shock and stun the world with. Players have arrived at the O2 arena in Prague, which has been outfitted with a black court.

Yes, entirely black.

The world hasn't seen competitive play on an all-black court at this level (though Metz was played on a dark gray court). It also hasn't seen Federer and Nadal play doubles together, which may be happening this weekend.

Other unorthodox changes at the Laver Cup including a deciding tiebreak in lieu of a third set. No player will be allowed to play singles more than twice over the three days. If the teams are tied at the end of regular play on Sunday, a deciding doubles set will be played.

Nothing seems to be off limits for this star-loaded exhibition.

Play begins on Friday, and each day features three singles matches and one doubles match.
