Andy Murray will reprise his coaching role with Novak Djokovic at the upcoming Indian Wells tournament and stay with the 24-time major champion for the Miami Open.
Djokovic, 37, plans to compete at both ATP Masters events - played back-to-back and known as the 'Sunshine Double' - for the first time since 2019.
Murray's team said the 37-year-old Scot flew out to the United States on Monday.
The Indian Wells main draw starts later this week, with the Miami Open following on 19 March.
Djokovic's last competitive outing was a first-round defeat by Italy's Matteo Berrettini at the Qatar Open on 18 February, when Murray was not present.
