Rafael Nadal is unsure if he'll play at the Rod Laver Cup in September
Rafael Nadal and Roger Federer united for the first time on a doubles court last September at the Laver Cup as they overcame Sam Querry and Jack Sock.
The second edition of the tournament will take place in Chicago between September 21-23.
Federer has already agreed to take part, along with Nick Kyrgios, while Novak Djokovic was recently added to Team Europe for the competition.
However, Nadal’s latest comments won’t come as good news for tennis fans as it looks like he won’t be forming another partnership with Federer.
The world No 1, who is currently competing against world No 2 Federer at Wimbledon, says his participation in the Davis Cup could stop him appearing in Chicago.
