Pakistan coach Bob Woolmer reckons the one-day series against England could be called off if Inzamam-ul-Haq is banned for bringing the game into disrepute.
Woolmer says a ban for Inzamam could spell further trouble
The Pakistan captain was charged after forfeiting the fourth Test at The Oval.
"If Inzamam is penalised and penalised heavily, which he could well be, then I cannot guarantee that my side will definitely play," Woolmer told the BBC.
Inzamam could be banned for up to four Tests or eight one-dayers when he appears at an ICC hearing on Friday.
Woolmer added he was not sure how the current controversy would be resolved.
"We'd like this all to go away and in fact we don't really want to be critical of umpiring, it goes against the spirit of the game," he told Newsnight.
"In this particular instance, unfortunately, it's gone just a little bit too far and so I don't quite know what the answer is."
The Pakistan Cricket Board had said it expected the series against England to go ahead despite Sunday's controversy.
"We intend to continue with this tour," said Pakistan Cricket Board chairman Shahriyar Khan.
The umpires awarded the fourth Test to England after Pakistan failed to come out promptly after tea in protest at being penalised for ball tampering.
Australian umpire Darrell Hair was seen as the prime mover in the decision to award five penalty runs to England and change the ball which prompted Pakistan's dramatic response.
He has not been appointed to stand in the one-day series, but Pakistan plan to tell the ICC they will not play any matches in future with him in charge.
Khan said a protest has been lodged with the ICC over Hair.
"We at the PCB would not want to see Mr Darrell Hair appointed to any Pakistan match in the future," he said.
"We have had problems with Mr Hair, the team has lost confidence in him and they feel deeply offended by his attitude towards the Pakistan team.
"Therefore we will feel his presence officiating in any match in which Pakistan is playing is not desirable."
Khan stressed the team had no problem with Billy Doctrove, who was the other on-field official at The Oval and is scheduled to stand in the first three one-dayers.
It was a very bad day for cricket - I've never seen anything like it
Former England skipper Alec Stewart
England and Pakistan are due to play a Twenty20 match at Bristol on 28 August, to be followed by five one-day internationals.
Meanwhile, former England captain Alec Stewart said it was vital the one-dayers do go ahead to ensure "relations between England and Pakistan are not damaged".
