CHENNAI (AFP) - International cricket chiefs insisted Saturday they had "full confidence" in their umpires after a former official reiterated his doubts about Muttiah Muralitharan's unorthodox bowling. Former Australian Test umpire Darrell Hair called Sri Lanka's Muralitharan, the leading wicket-taker in Tests and one-day internationals, for throwing in 1995. "A couple of current umpires have said to me, 'something is wrong', but they prefer to let it go," Hair told Melbourne's Herald-Sun newspaper ahead of Saturday's Sri Lanka-Australia World Cup match in Colombo. "There is still a lot of doubt about his deliveries." Hair said umpires were prepared to turn a blind eye as the player edged towards international retirement. But International Cricket Council chief executive Haroon Lorgat backed the international team of officials. "I've got full confidence in the elite panel of umpires, in the rules we have in place -- and it's up to the umpires to apply them."
