Bangladesh bowler Abdur Razzak faces an indefinite ban after being reported for suspected illegal bowling action.

''The left-arm spinner was reported by umpires Daryl Harper and Asoka de Silva at the end of the second Test between Bangladesh and New Zealand [Images] in Mirpur,'' the International Cricket Council [Images] said in a statement.

''In their report the umpires explained that they had concerns over the player's faster ball, and having monitored it during both matches in the series, decided it was appropriate the delivery should be scrutinized further under the relevant ICC [Images] process,'' the statement added.

The 26-year-old is required to submit to an independent analysis of his action by a member of the ICC panel of human movement specialists appointed in consultation with the Bangladesh Cricket Board.

The analysis must take place within 21 days of the report being received by the BCB. The report of the analysis must be filed with the ICC within 14 days of it occurring.

If the spinner is found to have bowled with an illegal action during the independent analysis, then he will be banned from bowling until he undertakes remedial action and is reassessed.

If the independent analysis finds the player guilty of bowling with an illegal action for a specific type of delivery only, then he can continue to bowl in international cricket with a warning that if he is reported again then he will be banned from bowling with immediate effect.

Razzak can continue to bowl until the BCB receives the report of the independent analysis.
