After receiving criticism on social media for his reaction to Cazaux collapsing, Mayot wrote: “Stop starting a false controversy for nothing.
“It had been several games since he didn’t feel well and he was starting to cramp.
“I didn’t see him fall and I thought he was lying down because he had a cramp. When I understood that it was serious I immediately followed go to him and I was very worried.
“I did my best to help. There is nothing but great friendship and complicity between us and always has been.
“You need to stop sending your hate all the time. I wish him a good recovery and the best.”
Cazaux is currently at a career high No74 in the ATP rankings.
Last week he reached the round of 16 in a Challenger event in Phoenix, Arizona, losing a tight match to former Wimbledon finalist Matteo Berrettini.
Earlier this year he enjoyed a huge breakthrough by reaching the fourth round of the Australian Open.
He beat Laslo Djere in round one before memorably producing a huge upset to knock out eighth seed Holger Rune in the second.
Cazaux backed up the result by trouncing 28th seed Tallon Griekspoor in round three.
He then bowed out to ninth seed Hubert Hurkacz in the last 16.
Following his huge result Down Under, Cazaux received a hero’s welcome back in his hometown Montpellier.
He performed a ceremonial kick-off at Montpellier’s Ligue 1 clash with Lille in January, before competing in the Open Sud de France the following week.
