STANDARDS SECTION XVIII - TOURNAMENT STANDARDS OF PERFORMANCE If vomiting is continuous, the PHCP may advise that continued  play is detrimental to the player’s health. In that case, the  Supervisor/Referee may retire the player from the match. If vomit has spilled onto the court, play must not resume until  the vomit spill has been cleaned appropriately. During the match, if there is an emergency medical condition, and  the player involved is unable to make a request for a PHCP, the  Chair Umpire immediately shall call for the PHCP and Tournament  Physician to assist the player. Either before or during a match, if a player is considered physically  unable to compete, or poses a serious health risk to players, officials,  or Tournament staff, the PHCP and/or Tournament Physician should  inform the Supervisor and recommend that the player be ruled  unable to compete in the match to be played, or retired from the  match in progress. The Supervisor/Referee shall use great discretion before taking  this action and should base the decision on the best interests of  Professional Tennis, as well as taking all medical advice and any other  information into consideration. Subject to the restrictions set forth in Section IV.C.2 - Matches  Scheduled Same Day, the player subsequently may compete in  another event at the same tournament if the Tournament Physician  determines the player’s condition has improved to the extent that  the player may safely physically perform at an appropriate level of  play and no longer poses a serious health risk to players, officials or  Tournament staff.  If during an on-court evaluation or MTO the PHCP deems it medically- warranted for the player to change her clothing, the PHCP could  include this during the MTO (performed off court at the closest/most  private location); otherwise, a clothing change only may be taken at  the end of a set. In the event there are simultaneous court calls, when a second  PHCP is not covering the Tournament, the PHCP will go to the first  iv.  Simultaneous Court Calls iii.
