Defending champion Rafael Nadal says he will be fit to take on Mardy Fish in the Wimbledon quarter-finals on Wednesday.
Nadal, 25, had a scan on Monday after suffering a foot injury in his fourth-round win over Juan Martin del Potro.
But any doubts that the world number one wouldn't make Wednesday's match were dispelled when he came through a full training session on Tuesday.
"Thankfully the tests don't show an injury. My foot is OK," Nadal said.
During a one-hour session on the Wimbledon practice courts the Spaniard wore tape on his left foot, but played without any obvious discomfort.
The Spanish Tennis Federation said the MRI scan that Nadal underwent on Monday night revealed only minor swelling on a tendon in his foot, rather than a broken bone as was initially suspected, and claimed there was no danger in him competing in the quarter-finals.
"There is no risk in him playing," said Dr Ignacio Munoz of the Spanish Tennis Federation.
"He is training quite normally. I don't think he will have any problems on Wednesday.
"He is having some physio and we have made some modifications to his taping that will help his support," Munoz added.
If Nadal gets past Fish and British number one Andy Murray beats Feliciano Lopez, the pair will meet in the semi-finals on Friday.
After completing an impressive four-set victory over Argentine Del Potro on Monday, a concerned Nadal said: "I don't know what the problem is, I will get it checked out. I'm worried for sure."
Nadal is unbeaten at Wimbledon since the 2007 final, but was unable to compete at the tournament in 2009 because of knee problems.
The Mallorcan had 10 minutes of treatment at the end of the first set of his win over former US Open champion Del Potro and had his foot strapped by the trainer.
He added: "I thought I had broken my foot, and when I asked for the trainer during the match I seriously didn't know if I could continue.
"With the tape it changed the direction of the support and it didn't hurt me that much."
Del Potro had his own injury scare during Monday's match, slipping and falling to the grass at 2-2 in the third set.
He remained on the ground, clutching his left hip and then left the court for treatment but returned within minutes to continue as Nadal won 7-6 (8-6) 3-6 7-6 (7-4) 6-4.
