Terence Atmane’s opening round battle at the 2026 US Open turned into a dramatic affair after the Frenchman lost his composure during a tense exchange with a tournament physiotherapist. Atmane had made an impressive start against Spain’s Jaume Munar, winning the opening two sets and moving within one set of securing his first ever Grand Slam main draw victory. However, his fortunes changed dramatically when severe cramping began affecting his movement. The physical problems became so severe that Atmane struggled to serve normally and was even forced to use his non dominant right hand after his left hand began seizing.

Despite the discomfort, he continued competing as Munar fought his way back into the contest. The situation escalated in the fifth set when Atmane called for the physiotherapist while trailing 2-1. The official declined to provide the treatment Atmane was requesting, reportedly determining that the Frenchman was suffering from cramping rather than an injury requiring a medical timeout. Under tennis regulations, players cannot receive standard on court medical treatment specifically for cramps. Atmane strongly disagreed with the assessment and insisted that he was experiencing pain rather than simply cramps. His frustration boiled over as he questioned the decision and demanded that the physio help him.

The exchange quickly went viral after cameras captured Atmane telling the physio to “stop acting stupid” and questioning whether there was any common sense in the situation. He also asked to see the official’s credentials as the tense confrontation unfolded. Despite the dramatic interruption, Atmane returned to the match and continued fighting. Munar, however, completed an extraordinary comeback, defeating the Frenchman 6-7(5), 3-6, 6-1, 7-6(4), 7-5 after nearly five hours of exhausting tennis. The defeat extended Atmane’s wait for a first Grand Slam main-draw victory. For Munar, meanwhile, the comeback secured his place in the second round, but the heated physio confrontation became one of the most talked about moments from the opening day of the US Open. The incident has also reignited discussion around how tennis rules handle cramping during long matches, particularly when players insist that their symptoms involve pain or injury rather than ordinary muscle cramps.
