Men's tennis is increasingly looking like the walking wounded. After Roger Federer's Australian Open victory, eyes are now turning to the French Open, but with plenty of questions surrounding some of the top stars will be healthy.

Federer appears to be the only elite player that isn't injured. Rafael Nadal, Novak Djokovic and Andy Murray have all battled injuries in recent months. Things are particularly bad for Stan Wawrinka, who has openly questioned his tennis future after knee surgery. Kei Nishikori, who missed the Australian Open with a wrist injury, has stated that his rehab is going well, but he isn't at full strength.

With the French Open set to begin in late May, here's a look at the health of Nadal, Djokovic and Murray.

Rafael Nadal

There continue to be fitness concerns surrounding Nadal after be bowed out of the Australian Open due to pain in his upper right leg on Jan. 23 in a quarterfinal match against Marin Cilic. He was initially diagnosed with a torn anterior hip muscle that would sideline him for three weeks.

The world No. 1 is expected to compete on Feb. 26 in the hardcourt Mexican Open in Acapulco. Nadal will likely address his health on Wednesday when he's interviewed at an event for Banco Sabadell.

Novak Djokovic

It must have been agonizing for the Serb to get eliminated in the Round of 16 at the Australian Open — easily his most dominant tournament. Djokovic admitted that his elbow is still bothering him after a long layoff in 2017, and flared up in his upset loss to Hyeon Chung on Jan. 22.

Before the Australian Open, Djokovic told reporters that his elbow had been bothering him for about 18 months. There has been no word as to whether Djokovic will compete in upcoming tournaments ahead of the French.

Andy Murray

Murray, who didn't compete in Melbourne, won't be playing at Roland Garros after hip surgery in Australia on Jan. 8. The Scot said he hopes to be ready for the grass court season in June.

On Jan. 20, Murray said his rehab was going "much better than expected."

In 2017, Murray missed a month due to an elbow injury.
