The England and Wales Cricket Board has again spoken to England captain Alastair Cook following his decision to defy new regulations and wear an old-style helmet. Officials from the ECB contacted Cook on Thursday to remind him of the new regulations after he refused to wear a helmet which meets new safety rules.Cook scored 105 and 35 not out in Essexs 10-wicket victory over Gloucestershire in their opening County Championship Division Two match this week. It is understood the umpires at Chelmsford and the ECB were aware that Cooks helmet failed to meet the new regulations, but chose not to enforce the new rules.New helmets which comply to British Safety Standard BS7928:13 have a smaller gap between the peak and grille and are not adjustable on each side.The rules were changed after numerous high-profile injuries, including to Stuart Broad and Craig Keiswetter, when a cricket ball penetrated beyond the helmets protective grille. Alastair Cook strides out to the crease at Chelmsford If Cook continues to use the Gray-Nicholls helmet, both county and Test umpires can ask him to leave the field.Cook has been made available for Essexs first four County Championship matches and is due to play next against Sussex at Hove on Sunday.He is due to lead the England team out again in the first Test against Sri Lanka at Headingley on May 19.Cooks Essex and England team-mate Ravi Bopara sympathises with anyone having to readjust to the new helmet style, but believes too that safety has to be paramount.I admit it myself, it is tough to start using those helmets - you do lose the ball for that less than a split-second, and that makes a whole load of difference to a lot of players, Bopara told Sky Sports News HQ. Ravi Bopara explains why Alastair Cook does not want to use a specific style of helmet. It makes them feel uncomfortable. So I understand where Cookies coming from. But when it comes to the guidelines and safety, we all have to be aware of that.Over a career, a batsman naturally becomes accustomed to the view of the ball his preferred helmet allows.Bopara added: Because of the safety aspect, with everything that has happened ... we are told we have to wear the helmets that meets the standard guidelines.It is difficult for players to change helmets like that, because you get so used to wearing a certain one which youre comfortable with - and you have your visor as wide as you want it.But the problem with the new helmets is you cant move the visors - youve just got to look at the hole thats there.Sometimes, that bar that goes across can get in the way.
