South Africa have lodged an official complaint after England number eight Lawrence Dallaglio escaped disciplinary action for apparently punching Springboks wing Thinus Delport.
Delport had stitches inserted into a cut around his eye suffered in a ruck late in England's 25-6 victory on Saturday.
Television footage appeared to show Dallaglio, held down on the ground, aiming a punch at Delport.
South Africa coach Rudi Straeuli confirmed his team had filled out official documentation to "seek redress" for the incident, even though the match citing commissioner has not taken any action.
"We've gone through the right channels," Straeuli said. "After the game there's documentation that you've got to put in, we've done that.
"We've lost a player, who's not playing this week. He has lacerations above his eye, and he's unhappy about that.
"The final discretion lies within the system and the citing commissioner."
South Africa are waiting to hear the result of their complaint.
"We would be disappointed if nothing happens, but we haven't
been notified yet," Straeuli added.
Under tournament rules, a citing commissioner has 24 hours from the end of a match to decide whether further action is taken.
Teams do not have the power to cite opposing players but can
refer any incidents of foul play to the disciplinary panel for consideration.
The citing commissioner then decides whether or not the player has a case to answer.
Dallaglio, for his part, defended his actions.
"He (Delport) had his hand in my face," Dallaglio said. "So I gave him a bit of a slap."
