The Russian third seed and 2004 champion suffered a painful second round exit at the hands of Portuguese qualifier, Michelle Larcher De Brito, the world 131, on the unfamiliar surroundings of Court Two on Wednesday.
Sharapova slipped three times, complained the surface was dangerous and needed an medical time-out to treat the left hip she injured in her falls.
She believes that players should be allowed to practice on the show courts at Wimbledon before the tournament gets underway to help them familiarise themselves with the conditions.
"The first few days, you just know that they're going to just be really different."

De Brito believes that Court Two was treacherous on Wednesday.
Earlier, former world number one Caroline Wozniacki fell and needed her ankle bandaged on her way to defeat to Petra Cetkovska.
"I saw how she fell pretty hard and I know these grass courts can be really slippery and can be quite dangerous," said Larcher De Brito, who took victory on a fifth match point.
