Lille have asked the French Football League (LFP) to rescind the yellow card shown to forward Anwar El Ghazi in Sunday's Ligue 1 win for removing his shirt to pay tribute to former teammate Abdelhak Nouri.
Nouri, 20, suffered severe and permanent brain damage after collapsing while playing for Ajax in a friendly against Werder Bremen in July.
El Ghazi, who moved to Lille in January, took off his shirt after scoring in Lille's victory over Nantes on Sunday to reveal a T-shirt emblazoned with Nouri's name and Ajax shirt number.
The 22-year-old was shown a yellow card by referee Benoit Millot in line with regulations, but Lille have pleaded mitigating circumstances in a bid to have the booking removed from the records.
"It was a strong and sincere gesture to which LOSC wishes to associate itself fully," a club statement read.
"Given the dramatic context that justified Anwar El Ghazi's gesture, LOSC has asked -- as an exception -- for the cancellation of the yellow card received by its player (for having taken his shirt off) by the LFP's Disciplinary Commission."
El Ghazi would face an automatic one-match ban if he were to receive three yellow cards within 10 appearances in domestic competition.
