New Delhi: Zimbabwe's Grant Flower has once again come under the microscope for a suspect bowling action, it was revealed here on Tuesday.The left-arm spinner, who was called for throwing by Australian umpire Darrell Hair in September, will have his action reviewed by the International Cricket Council (ICC).Former Australian cricketer Barry Jarman, who is the ICC's match referee for the ongoing Test match against India here, said in a statement that all of Grant's deliveries "were not legal"."After seeeing Grant bowl on Monday, both the umpires and myself were not entirely happy with the legality of all his deliveries," Jarman said in the statement. He added that a video tape of Flower's action will be sent to the ICC's bowling committee.The statement said, "Umpire Srinivas Venkataraghavan conveyed to Zimbabwe Captain Heath Streak on Monday that he was not entirely convinced that all of Grant's deliveries were legal, but could not get a clear view of him as he was behind umpire John Hampshire at a vital stage of his delivery."Jarman said he and the two umpires then viewed the film provided by Australian TV network Channel Nine, who are covering the Test. After watching the film, Jarman said they were satisfied with Flower's action in that particular delivery, but added that the action had not been cleared yet. "After viewing the film this morning, both umpires and myself were satisfied under the new law that Grant's arm was straight when it (arm) was level with his shoulder - however I will be sending the film to ICC for their decision", the statement said.Grant bowled 13.4 overs in India's first innings, conceding 54 runs without a wicket.
