Boris Becker fears Wimbledon may have seen the last of Serena Williams after she limped away from her first round match.
Williams slipped on the skiddy surface on Centre Court while leading Aliaksandra Sasnovich on Tuesday.
Although she tried to carry on, she was unable to compete and was forced to concede the match before leaving the arena in tears.
Serena is is 39-years-old now, and Becker worries time is quickly running out on her incredible career.
"It’s the last thing that a champion like Serena wants to do – leave her favourite courts with a walkover," Becker told the BBC.
"She can barely walk straight. We’ve got to get used to the fact that this might be the last time.
"She is past 30. It’s another year of coming back, injuries, wear-and-tear, she also had an injury at the French Open.
"It is sad to see but time waits for no man or woman.
"The courts seem to be a little bit slippery this year, a number of players have been complaining. Her left ankle went one way, her right leg went sideward.
"She must have strained whatever injury she already had. Unfortunately she had to quit."
