Porto defender Pepe was suspended for two matches on Tuesday after being accused of kicking an official from another team during a brawl in the Portuguese league last week.
The veteran Portugal international was red-carded for allegedly kicking a Sporting Lisbon club director during the altercation at the end of the 2-2 draw between the teams on Friday.
Sporting midfielder Bruno Tabata also was suspended for two matches after being accused of pushing a Porto club official during the brawl.
The suspensions for both players could be extended to up to two years after their cases are fully analysed.
They were among four players — two from each team — who were sent off.
Porto sits six points ahead of second-place Sporting at the top of the Portuguese league standings. Sporting is the current champion.
