National cricket coach Gus Logie has moved to quash fresh concerns over the legitimacy of spinner Hasan Durham?s bowling action following several complaints from opposing teams in the UK that the Western Stars stalwart was ?chucking?.

Guernsey coach and former England spinner Jack Birkenshaw, along with several of his players, told during Bermuda?s three-match series in the Channel Islands that they did not think Durham?s action was legal and that he should be prevented from bowling until the necessary adjustments had been made.

Those sentiments were shared by several members of Sussex Second XI after they had watched him bowl at East Grinstead Cricket Club on May 31.

It is also understood that several Namibian players voiced doubts during Bermuda?s controversial tour in November last year.

However, although Logie yesterday conceded that the left-arm spinner?s action is far from orthodox, he insisted there was nothing which contravened the laws of the game and rejected the suggestion that Durham should not be allowed to play until a bio-mechanical analysis had been conducted overseas.

?I really do not think there is anything to worry about,? he said.

?It certainly is not a classical action for a left-arm spinner ? it could not be more different from Dwayne Leverock?s for example ? and I think because of that it does look a bit suspect sometimes.

?But we have consulted a lot of highly-qualified people on the issue because this is not the first time this has come up.

?When we were in Trinidad, we asked (Test umpire) Simon Taufel to give us his assessment and he told us that as far as he was concerned, he was not able to see any problems with it.

?We will obviously continue to monitor Hasan, but when you?ve got one of the best umpires in the world telling you that there isn?t a problem, it means that we can be confident that there are no major issues with his action. He bowled very well for us in the UK and as it stands he is still very much part of our plans for the side.?

The subject of illegal bowling action has always been an emotive issue in cricket, and has become a particularly sensitive one since the emergence of Sri Lankan offspinner Muttiah Muralitharan. Before huge improvements in the television coverage of top-level cricket, whether a bowler was straightening his arm from a bent position on delivery was left exclusively to the judgement of the umpires.

Now, however, actions can be scrutinised in super-slow motion and every little kink or flaw laid bare ? something Durham will be exposed to for the first time if selected to play in the World Cup.

But what increased research has also shown is that virtually no bowler is capable of maintaining a perfectly straight arm through the course of a delivery ? a discovery which led to a recent re-jigging of an already complicated law which now allows leeway for a 15 degree ?flex? of the elbow joint.

The last international bowler to be banned for an illegal action was Pakistani seamer Shabbir Ahmed, who is nearing the end of a 12-month stint on the sidelines enforced by the ICC.
