The International Cricket Council handed Sarfraz Ahmed a four-match suspension on Sunday after a racist remark made by the Pakistan captain was picked up by a stump microphone in South Africa last week.
Sarfraz was heard making a comment in Urdu about Andile Phehlukwayo during last week's one day international in Durban, where the South African all-rounder earned a match-winning partnership with Rassie van der Dussen.
According to espncricinfo.com, the comment could be translated as: "Hey black guy, where's your mother sitting today? What prayer have you got her to say for you today?"
"The ICC has a zero-tolerance policy towards conduct of this nature," the global cricket governing body's chief executive David Richardson said in a statement.
Sarfraz later apologised for the comment on social media.
"I wish to extend my sincere apologies to any person who may have taken offence from my expression of frustration... My words were not directed towards anyone in particular and I certainly had no intention of upsetting anyone," Sarfraz wrote on Twitter.
"I did not even mean for my words to be heard, understood or communicated to the opposing team or the cricket fans."
The apology was given weight by the ICC as it handed out its suspension.
"Sarfraz has promptly admitted the offence, was regretful of his actions and has issued a public apology, so these factors were taken into account when determining an appropriate sanction," said Richardson.
Phehlukwayo seemed at ease about the incident after the match.
"It was good chat," he said.
Pakistan, who are currently playing a five-match one-day series in South Africa, will play three Twenty20 matches in Cape Town next month.
The country is ranked number one in Twenty20 internationals and have won nine consecutive matches, as well as a world record 17 out of the 19 T20Is they played last year.
On Saturday, Pakistan recalled fast bowler Mohammad Amir from the 15-man squad for the three-match Twenty20 series against South Africa.
The 26-year-old left-armer was left out of the limited-over and Test squads after a poor showing in last year's Asia Cup, but was brought back into both for the ongoing tour of South Africa.
