A TENNIS star was left bleeding from his face after hitting himself with a racket.<br /><br />But a legend of the sport slammed his suspicious injury.<br /><br />Frenchman Adrian Mannarino was taking on Italy’s Lorenzo Sonego at the United Cup in Sydney when the bizarre incident occurred.<br /><br />Mannarino won the first set 6-4 but found his tennis serve almost broken in the second.<br /><br />He then proceeded to bizarrely hit himself in the forehead with the butt of his racquet.<br /><br />Onlookers were stunned by Mannarino’s behavior.<br /><br />But they were even more blown away when it became clear that he had cut his head open in the process.<br /><br />A patch of blood could be seen seeping above Mannarino’s eyes.<br /><br />And the chair umpire stopped the match for a medical timeout, leaving Sonego incensed.<br /><br />He also reached the semi-finals of the 1987 Australian Open and the 1993 US Open.<br /><br />Masur questioned the timing of Mannarino’s self-inflicted injury, with Sonego turning up the heat at the same time.<br /><br />Speaking on commentary for Channel Nine, he said: “If [an injury] is self-inflicted, can you have a timeout? You can’t injure yourself, can you?<br /><br />“Let’s say you’re in a tricky situation, you go ‘right, I’m going to base myself with a racket and get a breather’.”<br /><br />Courtside commentator Mark Philippoussis quipped: “Perfect timing at 0-30, time to gather himself.<br /><br />“At the other end, I guess Sonego wouldn’t be happy. Now he has to cool off.”<br /><br />Masur continued: “Why has this taken so long? Get one of those little band-aids, the round ones.<br /><br />“This does not constitute a medical timeout in my opinion.<br /><br />“This is not a good look for the sport. This is not necessary. The way the trainers are, you would think he requires stitches.<br /><br />“Blood is not streaming from his head. It is like a pinprick. I have seen it all now.”
