Britain's Jack Draper has pulled out of this week's Miami Open as he does not want to make an abdominal muscle injury any worse.
The 21-year-old suffered a slight tear to his oblique muscle at Indian Wells.
He retired early on in the second set of a fourth round match against Carlos Alcaraz, who won the tournament and became the new world number one.
Draper, world number 43, suffered a series of retirements in 2021 but was able to play 22 events last year.
