Mumbai Indians captain Harbhajan Singh and Kings XI paceman S Sreesanth were on Friday involved in a bitter row, following which the fast bowler was seen crying bitterly on the ground at the end of their IPL match here.

Harbhajan allegedly slapped Sreesanth after the paceman said something to Harbhajan which offended the off-spinner.

The off-spinner however had a long chat with Sreesanth in the dressing room of the Punjab team and even believed to have apologised for his behaviour.

Harbhajan though did not speak on the issue when he came to address the post match conference.

"Can we have questions on just cricket," Harbhajan said when asked about what happened between him and Sreesanth.

The winning captain Yuvraj Singh was upset by the unsavoury incident and termed it "ugly".

"This is really an ugly incident. You do not want to see such things off the field specially after such a win. I am pretty upset at what has happened. This is totally unacceptable," he said apparently criticising Harbhajan Singh.

Yuvraj though said he did not know what actually transpired between the two.

"I do not know what exactly happened but one does not want to see such things happening."

Kings XI coach Tom Moody was also visibly upset by the incident and termed as "unacceptable" Harbhajan's behaviour.

"At the end of the day, players shake hands. But today saw more that from Harbhajan and Sreesanth. It is unacceptable behaviour and I am sure officials will take of note.

"The positive thing is that Harbhajan had a long chat with Sreesanth. But I am not sure what ramifications this incident will have," Moody said.

Upset after his team's third successive defeat, the turbanator also looked unhappy with his teammates.

"When you lose nothing seems to be okay. I won't bowl and bat for other people. They have to be captain of their own bowling and own bowling. I can not do other's job," he said angrily when asked if captaincy was tough.

"I don't like losing. When you lose, you don't feel happy."
