Sydney: West Indies batsman Marlon Samuels will not be sanctioned over a "throat-slitting" gesture he made in his team's World Cup win over Zimbabwe, a source told AFP on Thursday.

Samuels appeared to run his thumb from one side of his throat to the other to mark his century in Tuesday's 73-run victory. "The match officials have seen the incident and have decided not to lay a charge," said a source.
