Rafael Nadal says he is in a “difficult” situation as he does not know when he will return from his injury lay-off.
He was initially ruled out for six to eight weeks with a hip injury but has now not played since 18 January.
Nadal confirmed he will miss the Madrid Open, which starts on 25 April, and there is doubt over his participation at the French Open in May.
Nadal, who won his 14th French Open title last year, was diagnosed with a tear in his left psoas muscle after losing in the second round of the Australian Open in January.
