JACK CROWLEY could not hide his anger as he launched into a foul-mouthed rant during Munster's dramatic defeat to the Sharks. And Premier Sports pundit - and former Ireland and Munster star - Alan Quinlan accused the opposition sideline of 'shocking behaviour'. Ian Costello's men were knocked out following a thrilling penalty shoot-out in Durban on Saturday. 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 boiled over during the shoot-out however. It 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." Saturday's defeat was the final game in the Munster careers of Peter O'Mahony. Conor Murray, and Stephen Archer. O'Mahony and Archer will be hanging up the boots for good at the end of the season, while Murray will be continuing his career abroad. And interim Munster head coach Ian Costello paid tribute to the departing trio. He said: "Those three are exceptional people and legends of Munster rugby. “And they’ve left, or they will leave, a massive legacy behind. That's going to be very difficult for us to live up to and fill, but that's what you want. “You want somebody to leave it in a better place. And they've left the jersey in an unbelievably good place. "Now it’s for everyone else in the dressing room, moving on to next year, to live up to that. “There's also our team manager, Niall O'Donovan, who's an even longer servant of Munster rugby. It was his last game as well. "The last few weeks have been pretty special in terms of making sure those boys got a good send-off, which is why tonight was particularly disappointing.”
