Australia were left fuming as England's Stuart Broad enjoyed a massive slice of luck on the third day of the first Ashes Test at Trent Bridge on Friday.
Broad, on his Nottinghamshire home ground, had made 37, with England then 297 for seven in their second innings, when he edged teenage debutant spinner Ashton Agar.
The ball clipped wicketkeeper Brad Haddin's gloves and then flew to Australia captain Michael Clarke at first slip.
Australia appealed for the catch but leading Pakistani umpire Aleem Dar ruled in the batsman's favour as Broad stood his ground.
The tourists couldn't believe the verdict but ultimately, as they'd already used up both their two permitted reviews in the innings, they had to accept it.
Australia coach Darren Lehmann's anger on the dressing room balcony was clearly visible after television replays showed Broad had got a thick edge.
Earlier on Friday, Australia ran out of reviews when they decided to challenge a not out verdict following James Pattinson's hugely optimistic lbw appeal against Jonny Bairstow, which replays showed was missing leg stump.
'Walking', the practice whereby batsmen gave themselves out without waiting for the umpire's decision, was once a long-established practice in English county cricket and 'non-walkers' were considered unsporting.
However, the custom in Australian cricket, from even as far back as batting great Don Bradman's time, has been to wait for the umpire's verdict.
Despite former Australia wicketkeeper Adam Gilchrist, who retired from international duty in 2008, being a noted 'walker', few other modern players have copied his lead, particularly now that decisions can be challenged by recourse to technology.
