England captain Alastair Cook was unhappy with Dar for changing one of the match balls in their defeat to Sri Lanka at The Oval last week, leading to speculation of ball tampering.
And the British media speculated that the ball change incident might be a reason behind ICC's decision to exclude Dar from on-field duties.
"England have been spared one potential concern in the Champions Trophy final with Aleem Dar relegated to the peripheral fourth umpire role," a report in the 'The Guardian' said today.
Kumar Dharmasena and Rod Tucker have been named as the on-field umpires for tomorrow's final between India and England, while Bruce Oxenford will discharge the duties of the third umpire.
