London: World governing body FIFA yesterday announced disciplinary proceedings against West Ham United and Diafra Sakho over the striker's failure to play for Senegal at the Africa Cup of Nations.
Sakho was ruled out of the tournament in Equatorial Guinea with a back injury, but came off the bench to score for West Ham in their FA Cup fourth-round win over Bristol City on January 25.
West Ham have maintained that they followed the correct procedures, but Sakho was left out of their squad for Saturday's 0-2 loss at Liverpool in the Premier League.
"We can confirm, that disciplinary proceedings were initiated against the player Diafra Sakho (SEN) and the club West Ham United for a potential violation of the FIFA Regulations on the Status and Transfer of Players," FIFA said in a statement.
If FIFA's case is proven, Sakho could face a suspension and West Ham a fine.
