request, unless otherwise advised of a medical emergency. 

If there are two (2) court calls on the same court the following procedure will occur: 

(a) The PHCP will go to the first request or medical emergency, administer a complete evaluation and MTO, if indicated, then; 

(b) Go to the second request and administer a complete evaluation and MTO, if indicated; and 

(c) The PHCP will rotate treatments on the change of ends, if necessary, beginning with the player who had the first request, until the process is complete. 

In the event the PHCP determines both court calls to be muscle cramping, the PHCP will treat the player who had the first request for sixty (60) seconds (as timed by the Chair Umpire) and then treat the second player for the remaining sixty (60) seconds of the 120 second change of ends, or treat each player for ninety (90) seconds during a set break. 

v. Warm-Up Period 

With regard to the Medical Rule, the match includes both the warm-up and play; thus, any medical condition incurred during the warm-up is considered a medical condition during the match. 

If a player sustains an acute treatable medical condition during the warm-up that prevents the player from starting the match as scheduled, the player can receive either a MTO or ninety- (90) second treatment period at the end of the warm-up, prior to the start of the match. 

If the MTO is taken during the warm-up, the five- (5) minute warm-up shall be suspended until the conclusion of the MTO. If it is clear the player is not physically able to compete after receiving treatment, then the match should not begin.
