"We'll see what the weather is like," Lendl told the British media. "If the weather is good, I am sure we will practice."
Asked whether he was concerned about
"I wasn't really surprised," Lendl added. "The first match on grass is always tricky. The guys who beat Stan Wawrinka, Milos Raonic and Andy had played qualifying or the previous week at a tournament. We have seen that movie over and over.
"Guys play matches, feel a little bit more comfortable than the guys who don't play, " the 57-year-old further said.
Roger Federer, seven times a champion at the All England Club, said he was convinced
"I expect him to play unless I have missed something completely," the Swiss told British newspapers.
"I would know more about it, I think, if it had been a really significant injury. The way I know Andy, he's tough as nails and I feel like he’s going to be there on the opening Monday.
"He would need to be significantly injured not to play. For me, if he can get through that first round and feel better afterwards, absolutely he should play, " Federer further commented.
