Murray, a three-times Grand Slam champion, underwent hip resurfacing surgery in January last year but returned to win the Antwerp title seven months later -- his first since 2017.
The 33-year-old Briton missed most of the 2020 season due to complications with his hip and struggled for form on his return after the Covid-19 hiatus, suffering a second-round defeat in the US Open before falling in the opening round at Roland Garros.
