Upset over the row between Mumbai stand-in captain Harbhajan Singh [Images] and Punjab paceman S Sreesanth [Images], Indian Premier League Chairman Lalit Modi on Saturday said it was a "serious matter" and was not good for the cash-rich Twenty20 tournament.

But Modi said the IPL committee would wait foar an official report on the matter before deciding about their next action in the issue.

"It looks like a serious matter the way it's being shown on television channels but I can't say anything now. In any tournament it should not happen, it's unfortunate what happened yesterday," Modi told reporters in Chandigarh.

Harbhajan allegedly slapped Sreesanth after Mumbai Indians lost their IPL match to Kings XI Punjab last night and the paceman was seen bitterly crying on the field.

Modi, however, said the IPL committee could take any decision only after receiving an official report on the matter as picture was still not clear about what exactly happened between the two players last night.

"The incident in itself is sketchy. There is no clear evidence at this moment, there are different versions about what may have happened. But at the end of the day we have to take cognizance of the fact that happened on the field.

"(So) we are waiting for the match referee and umpire's report only after which our committee will take a decision. The tournament is being played under the ICC [Images] guidelines, besides there are also tournament guidelines for the players," he said.
