Roofe was sent off during the 2-0 home defeat to the Czech side in the Europa League after kicking goalkeeper Ondrej Kolar in the face.
Kolar was left with a fractured skull and the governing body has now cited him for "dangerously assaulting another player".
In an ill-tempered affair at Ibrox, Glen Kamara and his Rangers team-mates reacted furiously as they claimed Czech defender Ondrej Kudela had whispered a discriminatory slur into the midfielder's ear while cupping his hand.
Slavia rejected the racism claims and accused Kamara of assaulting Kudela in the tunnel after the final whistle.
For their part in the fracas, Rangers have been fine 9,000euros (£7,826) after being found guilty of improper conduct.
Kudela was handed a one-match provisional ban while UEFA investigated the incident and he did not play in Slavia's 1-1 draw at Arsenal last week.
