MIAMI GARDENS, Fla. — Daniil Medvedev officially withdrew from the Miami Open on Wednesday, citing unresolved safety concerns stemming from the chaotic umpire incident that disrupted his second-round match against Francisco Cerundolo, tournament organisers confirmed. The world No. 4 released a statement through his management team saying he could not in good conscience continue competing until the ATP provided clearer protocols for player and official protection during on-court emergencies.
The incident, which halted play for nearly 40 minutes on Tuesday evening at Hard Rock Stadium, involved a chair umpire losing consciousness mid-match in sweltering late-March heat. Medvedev, visibly shaken courtside, reportedly told tournament referee Carlos Bernardes that structural changes were needed before he felt safe returning. His withdrawal hands a walkover quarterfinal berth to his scheduled opponent, Italian rising star Matteo Arnaldi.
ATP Tour chief Andrea Gaudenzi convened an emergency working group Wednesday morning, bringing together tournament directors, the Professional Tennis Players Association, and medical staff from the WTA and ATP circuits. Sources familiar with the discussions said the group is weighing mandatory cooling breaks every four games during sessions when the heat index exceeds 95°F, as well as a standing reserve umpire seated courtside at all times during extreme weather conditions.
The episode has sent ripples through the remainder of the Miami Open draw. Several players, including Holger Rune and Tommy Paul, made public statements on social media Wednesday expressing solidarity with Medvedev's position. Tournament director James Blake held a press conference at noon local time, promising that all remaining matches would include enhanced medical personnel at courtside and that ball kids would receive mandatory hydration breaks at changeovers.
Medvedev's withdrawal marks the second high-profile ATP retirement or withdrawal of the North American hard-court swing and raises broader questions about scheduling summer-adjacent tournaments in Florida during increasingly extreme weather. The ATP is expected to publish preliminary findings from its emergency review by Friday, with a full policy report due ahead of the French Open in late May. The Miami Open quarterfinals are set to proceed Wednesday evening with the adjusted draw in place.
