Scott Brown and Steven Naismith will face no action from the Scottish Football Association following incidents in Hearts' win over Celtic.
It was alleged Brown had elbowed Hearts forward Naismith, who was accused of kicking out at Celtic winger Jonny Hayes in a separate clash.
The SFA has introduced a new system in which a panel of three former category one referees review contentious issues.
A unanimous decision to award a red card is required but was not reached.
Hearts won 1-0 on Saturday to go clear at the top of the Premiership.
