Paris - South African flyhalf Morne Steyn has been suspended for two weeks pending a French National Rugby League disciplinary hearing, the LNR said on Tuesday.
READ: I didn't deserve red
The 30-year-old was red-carded in Stade Francais' 12-9 defeat at Lyon last Friday which saw them lose the Top 14 leadership.
The LNR said Steyn, the top-scorer at the 2011 World Cup, would appear before their disciplinary commission on January 22.
"(Steyn) is suspended awaiting the meeting," the LNR added.
Steyn had confidently kicked Stade into a 6-0 lead courtesy of a 40-metre penalty and a drop goal.
But after Mosese Ratuvou had cut the deficit with the night's opening try, Steyn saw red in the 31st minute for kicking the Fijian winger as the two tussled on the ground.
It left Stade to play 50 minutes with 14 men and Lyon took full advantage when Ratuvou added a second try early in the second period.
Ratuvou was also called before the disciplinary commission for the incident but not suspended.
Three other Top 14 players were also called before the LNR but not suspended - Remi Lamerat (Castres), Olivier Missoup (Oyonnax) and Thomas Synaeghel (La Rochelle).
