Stan Wawrinka will miss Wimbledon due to the foot injury which also ruled him out of the French Open.
Former world number three Wawrinka underwent an operation on his left foot earlier this year and now will miss SW19, according to the ATP.
The 36-year-old Swiss has not played on the ATP Tour since his opening-round defeat by Lloyd Harris at the Qatar Open in March.
Wimbledon starts on June 28, with the tournament back for the first time since 2019 after being postponed last year due to the pandemic.
Three-times Grand Slam champion Wawrinka has competed at the All England Club on 15 occasions, reaching the quarter-finals in 2014 and 2015.
He won the Australian Open in 2014 before adding the French Open (2015) and U.S. Open (2016) titles to his trophy cabinet.
The world number 24 is in rehabilitation at his base in Monaco.
His spokeswoman told Reuters last month that the player hoped to be fit for the grasscourt season.
