During the England vs Australia semifinal Kumar Dharmasena and Jason Roy were involved in a controversial spat. In addition to the fine, two demerit points have also been added to his disciplinary record.
"The dissent he showed was nearly soccer-like, up, remonstrating with the umpires", he said. But Cowan believes he should have copped a much more serious punishment, saying he should have been banned for a match.
"What he did was an absolute disgrace".
Dharmasena was a bit late to give his decision, leaving Roy angry.
"I've never seen that on a cricket field".
"Honestly, he's been watching too much Premier League soccer. You can not treat umpires like that on a cricket field".
Roy was hit with his second fine of the World Cup, having unleashed a foul-mouthed tirade at an umpire while marching England to victory over Australia, but the in-form opener is in no doubt of missing Sunday's final through suspension. Roy could not contain his disbelief when the Sri Lankan gave him out caught behind off Pat Cummins 15 runs shy of what would have been a 10th one-day worldwide hundred, and was subsequently hit with two demerit points on his record following England's brilliant eight-wicket win over Australia at Edgbaston.
"It's professional sport, emotions run high", the 28-year-old said.
Roy was fined for showing dissent at the umpire's decision after he was wrongly given out caught behind. He raised his bat to soak up the applause of an adoring Birmingham crowd, who appreciated his valuable knock in taking England one step closer to what would be a maiden World Cup triumph. An appeal by Aussie wicketkeeper Carey was hesitantly upheld by Dharmasena.
After Australia were all out for 223 in 49 overs, England opener Jason Roy struck a superb 85 from 65 balls as he put on yet another big stand with Jonny Bairstow to break the back of the run chase.
