Australian world number two Lleyton Hewitt remains hopeful he will play at the French Open starting next Monday despite fracturing a rib in a fall this month.
Hewitt sustained the injury at his Sydney home two weeks ago, forcing him to delay his comeback at the World Team Cup in Germany.
Hewitt's manager Rob Aivatoglou said a final decision would have to be taken by Friday to allow the player to get to Paris on time.
"We're still holding out some hope although, obviously, the odds get longer the more time goes by," Aivatoglou told Australian media.
Hewitt, whose fiancee Bec Cartwright is expecting a child later this year, has not played since injuring his toe after losing to Roger Federer in the final at Indian Wells in March but definitely plans to compete at Wimbledon.
Australia's top-ranked female tennis player, Alicia Molik, has returned to training after being forced to pull out of the French Open.
Molik was sidelined for five weeks with a middle-ear infection but has begun her preparations for Wimbledon where she could be a genuine contender.
"I would have loved to have played in Paris and I would have loved to have been playing in the last month-and-a-half," Molik said.
"When I'm ready to play, I'll be ready to play at 100 percent."
