Bangladesh edge Sri Lanka in highly controversial Cricket World Cup clash

After Sadeera Samarawickrama was caught on the deep mid-wicket boundary with Sri Lanka on 135 for four, Mathews walked to the crease with the bat in hand but appeared to notice his helmet strap was broken before marking his guard.

The Sri Lankan number six signalled for a new helmet before facing a ball and Bangladesh captain Shakib Al Hasan then appealed to the umpire for the batter™s wicket, as he was not ready to face his first ball within the two minutes required by the competition rules.

After much deliberation and no withdrawal of the appeal, Mathews was forced to walk off the field having not faced a ball.

While within the laws of the game, questions will be asked over whether the dismissal is also within its spirit.

The World Cup rules state that "after the fall of a wicket or the retirement of a batter, the incoming batter must, unless time has been called, be ready to receive the ball or for the other batter to be ready to receive the next ball within two minutes of the dismissal or retirement. If this requirement is not met, the incoming batter will be out, timed out."

Former Pakistan captain Waqar Younis was disappointed with the events he saw on the field.

He said on Sky Sports: "I didn't enjoy what I saw out there. The spirit of the game, I always believe in that and the appeal and whole drama, I thought it was a bit too much for my liking.

"He came at the crease and he was standing there when he tried to pull that strap and the strap came off and he was just asking for another helmet.

"Yes, he came out a little bit late and in the law of the game he is out, but spirit of the game, I didn't like it."

Fourth umpire Adrian Holdstock explained the decision making and revealed Mathews had already gone beyond two minutes before he realised his helmet strap was broken.

He said: "When it comes to timed out, the incoming batter has to be in position and ready to receive a ball within two minutes and we have certain protocols where the TV umpire at a fall of the wicket monitors the two minutes and he will relay the message on to the on field umpires.

"In the instance this afternoon, the batter wasn't ready to receive the ball within those two minutes, even before the strap became an issue.

"The fielding captain initiated the appeal to Marais Erasmus that he wanted to appeal for timed out."

Bangladesh went on to take their second victory of the tournament with a three-wicket win.

Charith Asalanka's second ODI century proved to be in vain as he helped Sri Lanka reach 279.

In reply, a key partnership between Najmul Hossain Shanto (90) and Shakib (82) took the game away from Sri Lanka as Bangladesh picked up their first win since their opening fixture against Afghanistan.
