Andy Murray has recovered from an injured ankle and will play in the Aegon Championships at Queen's.
The 24-year-old suffered ligament damage in his right ankle and was using painkillers.
But he practised for two hours on Monday and will play in the doubles with brother Jamie on Tuesday.
"It's definitely better than it was," said Murray. "It was a bit sore when it happened but it should be OK."
Murray received a first-round bye in the singles draw and will face either Xavier Malisse of Belgium or German world number 99 Matthias Bachinger on Wednesday.
He revealed he is looking forward to getting back on to the grass courts and aims to build on an impressive showing in Paris, with his run halted in the last four by Rafael Nadal, who won his sixth French Open title on Sunday.
"It takes time [to adapt to grass]," added Murray. The only negative about doing well at the French Open is less time to prepare for grass but I'd rather be in this position.
"This is one of the nicest tournaments to play. I really enjoy it. I played well here in the past and it's the perfect preparation for Wimbledon."
Janko Tipsarevic of Serbia, seeded 14th, is a possible third-round opponent, while Croatia's Marin Cilic and four-time champion Andy Roddick are potential quarter-final and semi-final opponents respectively.
Wimbledon starts on 20 June and Murray, the 2009 Queen's Club champion, will be desperate to be 100% fit as he renews his quest for a first Grand Slam title.
World number two Novak Djokovic pulled out of the tournament last week with a knee injury, while number three Roger Federer has withdrawn from his favourite pre-Wimbledon tournament in Halle, because of a groin problem.
Top seed Nadal, like Murray, also received a first-round bye at Queen's.
