Achraf Hakimi was sent off for Paris Saint-Germain as the Ligue 1 leaders played out a 0-0 draw with Marseille in Le Classique on Sunday.
Mauricio Pochettino's side, who started with the heralded trio of Lionel Messi, Neymar and Kylian Mbappe, largely struggled to break down their stubborn hosts, even before Hakimi's dismissal in the 57th minute for a foul on Cengiz Under.
Valentin Rongier and Konrad De la Fuente wasted glorious opportunities to find a winner in the closing stages as PSG ultimately held on to take a point back to the capital.
The result means PSG are seven points clear at the Ligue 1 summit, while Marseille are 10 points behind in fourth, although Jorge Sampaoli's side have a game in hand.
PSG thought they had taken a 14th-minute lead when Luan Peres diverted Neymar's mis-hit shot into his own net, but a VAR review showed the Brazilian was in an offside position.
Marseille had an effort of their own ruled out seven minutes later, Pol Lirola straying into an offside position before Arkadiusz Milik found the back of the net.
Moments after Pau Lopez tipped a Lionel Messi header onto the crossbar referee Benoit Bastien stopped play for a few minutes after projectiles were thrown at Neymar as he tried to take a corner.
PSG's hopes of claiming all three points were dealt a blow in the 56th minute when Hakimi was shown a straight red card for bringing down Under outside the penalty area as he bore down on goal.
An unmarked Rongier inexplicably headed wide in the 65th minute, while Konrad fluffed his lines when the ball fell kindly to him at the back post as the game petered out for an uninspiring draw.
