Snooker star Stephen Maguire appeared to eat something off the baize during his quarter-final match against David Gilbert.<br /><br />The bizarre incident happened in the 19th frame with the Scotsman trailing his rival by 11-8 at the World Snooker Championship at the Crucible in Sheffield.<br /><br />Maguire looked at the table after playing a shot and seemed to pick something off it, before proceeding to eat it and carrying on with the match seemingly unperturbed.<br /><br />And the Glaswegian subsequently revealed he'd eaten a fly.<br /><br />'It was just a fly. I spat it out when nobody was looking,' he told Metro Sport. <br /><br />The strange interlude did not help his quest to reach the semi-final of the world championship as he crashed out 13-8 against Gilbert, who will face either Kyren Wilson or John Higgins in the semi-finals.<br /><br />It is not the first time in this tournament that Maguire has made the headlines for his behavior at the baize.<br /><br />Earlier on Wednesday, the Scotsman punched the table after playing a poor positional shot against Gilbert.<br /><br />As he moved around the table looking to work out his next shot, Maguire punched the baize in frustration before walking back to his chair.<br /><br />'He can't disguise his annoyance, his anger,' said Eurosport commentator Phil Yates.<br /><br />'Why does he do it? One of these days he'll regret it in a major way. Yes, show frustration, but not like that.<br /><br />'I like Maguire's passion, I just don't want to see him hurt himself.'
