JESSICA O'MAHONY expressed her disappointment at Jaden Hendrikse for a moment that led to a foul-mouthed outburst from Jack Crowley. The Sharks star went down with an apparent cramp after converting a penalty during the shoot-out win over Munster on Saturday. Due to where he went down, Hendrikse received treatment nearby to where Jack Crowley was due to take the next kick. Peter O'Mahony's wife Jessica took to Instagram to share her disgust at the act of alleged gamesmanship. She took a photo of the scrum-half undergoing treatment alongside the caption: "This guy? Bad form". Despite the potential distraction, Crowley showed his composure to slot the kick between the uprights. But that did not stop the 24-year-old from directing his frustration at the Sharks head coach John Plumtree. It was the culmination of tensions that had bubbled up during the shoot-out. Jack Crowley, Conor Murray, and Rory Scannell stepped up for the Irish province, while the Sharks were represented by Jaden and Jordan Hendrikse and Bradley Davids. Scannell was the only one of the six to miss as the Sharks ran out 6-4 winners to set up a United Rugby Championship semi-final against the Bulls for June 7. Tensions started when Jaden Hendrikse had words for Jack Crowley after converting his first kick, leading to a warning from referee Mike Adamson. He was at it game after converting his side's third, as he went to ground with a supposed cramp. As Hendrikse was receiving treatment, he was laid nearby to where Crowley was to take the next kick, and even directed a wink at the Ireland international. Despite the potential distraction, Crowley nailed the kick before directing his ire at Sharks coach John Plumtree. While it could not be definitively deciphered what he said, he could been seen saying "f*** off" at the end of the exchange. The jostling did not stop there, with Scannell gesturing towards the Sharks sideline after nailing a later kick of his own. Speaking on Premier Sports, former Munster star Alan Quinlan criticised the behaviour of the Sharks sideline. He said: "It's shocking really, the way they're behaving, the people on the sideline there. "They're obviously screaming and shouting stuff at the Munster players. "It's obviously not very sportsmanlike. Unlike Rory Scannell there to respond as well."
