England will be left searching for another new one-day captain if Paul Collingwood is banned for four matches. Only a successful appeal can save him from serving the International Cricket Council's minimum sentence after his team was found guilty of being three overs behind the clock during yesterday's dramatic game at The Oval.

As captain, Collingwood is held responsible for England's slowness in the field and last night's guilty verdict was the second recorded against them since he took over 12 months ago.

That means an automatic ban for Collingwood - with a minimum sentence of four one-day internationals, or two Tests, or a combination of the two - unless the Durham all-rounder appeals today and wins his case.

But if Collingwood accepts the punishment, which should come into effect immediately, then England will need a new skipper for Saturday's final meeting with New Zealand at Lord's.

Given that Kevin Pietersen was the only other candidate to replace Michael Vaughan last summer, the selectors are likely to look towards the team's most flamboyant character.

Longer term, Collingwood could pay a huge price for England's sluggish over-rate. If his ban is confined to one-dayers, he will also miss the first three games against South Africa in August and there would be no guarantee of him getting his job back.

Alternatively, Collingwood could be out of the start of next month's Test series, and his hold on a place in that form of the game is already tenuous.

Over rates have long been a problem for England, even though lenient umpires and referees often let them off the hook. Last night, though, when almost everyone else was talking about a dramatic last-ball finish and Collingwood's refusal to withdraw a run-out appeal against Grant Elliott, the match officials decided to act.

In fact, Graeme Swann's decision to go for glory probably saved Collingwood from landing himself in double trouble because a one-wicket win went a long way towards soothing New Zealand's anger about the Elliott incident.

Unlike Collingwood's decision, Swann's attempt to throw down the stumps and win the game for England really was a split-second reaction.

Swann had no time to put his thinking cap on, hurled at the stumps from short cover as Mark Gillespie lumbered down the pitch and not only missed the target but also managed to thread the ball between four fielders to concede the extra run that handed the visitors victory.

Given another chance, Swann would surely steady himself and lob the ball towards the stumps so that, at the very worst, England could achieve a tie.

But if he had secured a win for the home side then it is a fair bet New Zealand would not have been nearly so willing to accept either Collingwood's explanation or his apology, leaving Saturday's series-deciding match to be played out in a poisonous atmosphere.

Elliott, who had helped New Zealand to get within 26 runs of their victory target of 246, was on the ground, receiving treatment, for a couple of minutes after colliding with bowler Ryan Sidebottom while going for a 44th-over single.

Sidebottom said he was going for the ball. But, in doing so, he veered into the batsman's path, leaving Elliott unable to avoid a nasty collision.

Umpire Mark Benson had no option but to give Elliott out once Ian Bell and Pietersen completed the run-out. But England could have withdrawn their appeal and Collingwood had longer than a split second to consider the matter.

"In hindsight, I wished I had called him back," he said.
