St Mirren loanee Esmael Goncalves has accepted a two-match suspension for simulation.
The Portuguese striker, on loan from Rio Ave, was charged by the Scottish Football Association for breaching rule 202, which refers to 'causing a match official to make an incorrect decision by committing an act of simulation.'
The incident occurred in St Mirren's 1-1 draw with Celtic when Goncalves went down in the box under a tackle from Eilio Izaguirre which won the Buddies the penalty to equalise the score.
Goncalves, who scored the opening goal in the 1-1 draw with Kilmarnock on Tuesday night, will miss Saturday's meeting with Motherwell as well as the Budies' first match when the SPL splits.
