Pakistan's vice-captain Salman Butt [Images] has been fined 50 percent of his match fee for his outburst against some of the umpiring decisions in the Test series against South Africa.

International Cricket Council match referee Alan Hurst said Butt had been fined after being found guilty of public criticism and inappropriate comment on a match-related incident or match official.

Butt criticised some umpiring decisions on Thursday during the second Test, saying they had gone against Pakistan.
