Emma Raducanu has withdrawn from the Miami Open due to illness.
The 23-year-old British number one was given a bye in the second round of the tournament, which begins on Tuesday.
Raducanu is still recovering from symptoms following the virus, which he contracted in the Middle East last month.
The 2021 US Open champion competed in Indian Wells earlier this month, but lost to Amanda Anisimova 6-1, 6-1 in the third round.
After losing in 52 minutes, Raducanu admitted he couldn’t muster enough strength to compete with the two-time Grand Slam finalist.
She repeatedly refused to pursue drop shots and struggled to put pressure on her opponent on return of serve.

Raducanu ended his relationship with his latest coach, Francisco Roig, in January and has been working with Mark Petchey on an ad hoc basis in a bid to rediscover his top form.
The 24th seed could face compatriot Sonai Kartal, who will face American Peyton Stearns, in the round of 64 in Miami.
