A Djokovic / Dimitrov exhibition right after the US Open!

Novak Djokovic is enjoying his Olympic triumph and is not expected to return to official competition until after the US Open.

That said, we've just learned a little more about the Serb's schedule and it would appear that he has decided to accept the invitation of his rival and friend, Grigor Dimitrov.

On September 17, the two men will face off in Sofia in a charity exhibition match organized by the "Grigor Dimitrov Foundation" (a foundation supporting Bulgarian children).

A choice which probably explains the absence of both men at the Laver Cup (September 20-22).
