Neymar was carried off on a stretcher as Kylian Mbappe became the youngest goalscorer in Le Classique history, with the teenager on target in an easy 3-0 Ligue 1 win for Paris Saint-Germain against rivals Marseille.
PSG needed an injury-time free-kick from Edinson Cavani to claim a draw in the reverse fixture - in which Neymar was sent off - but there was no such drama at the Parc des Princes on Sunday until the Brazilian suffered a suspected ankle injury in the closing stages.
Unai Emery's men, who have won all 14 of their home league games this season, move 14 points clear at the top of Ligue 1 as a result of their victory, with Marseille remaining third.
Mbappe gave PSG an early lead, capitalising on left-back Jordan Amavi losing his footing to run on to a Dani Alves pass and slot in a well-taken finish.
Rolando's own goal doubled PSG's lead 17 minutes later, the defender only able to turn Neymar's effort past goalkeeper Yohann Pele with Cavani lurking behind him.
Neymar was a doubt for the game due to illness but he set up Cavani for a brilliant third after half-time to ensure PSG have a hand on the Ligue 1 trophy with 11 games still to play.
Marseille will have an immediate chance to earn revenge in Wednesday's Coupe de France quarter-final, however, with Neymar's participation in that tie questionable after he appeared to roll his right ankle.

Marseille were in front twice in a 2-2 draw in Le Classique earlier in the season but PSG took the lead in the 10th minute.
Alves played a throughball into the box for Mbappe, with a slip by Amavi allowing the teenager to collect the pass and send Pele the wrong way with a smart low shot.
Neymar got above Hiroki Sakai to head wide before Lucas Ocampos was fortunate only to be shown a yellow card for a bad late tackle on Alves.
PSG were dominant and their second arrived after 26 minutes, Rolando scoring an own goal.
Adrien Rabiot combined with Layvin Kurzawa on the left and although Neymar's first-time shot was heading wide of the far post, Rolando had to try to clear with Cavani ready to tap in, but the defender could only divert the ball beyond Pele.
Neymar bent a superb strike narrowly wide and Marseille coach Rudi Garcia hauled Ocampos off before the break, bringing on Morgan Sanson in a bid to give Marseille a foothold.
PSG continued to control the match after the interval, though, with Cavani wrapping up the points after 55 minutes.
Neymar's dazzling run and cross created the opportunity for Cavani, who took a sublime first touch, held off and turned Rolando and smashed home an unstoppable finish to score in his third successive Classique appearance.
Rolando almost made amends for his own goal, but Alphonse Areola turned his looping header around the post.
But there was bad news as Neymar damaged his ankle in an innocuous challenge with Bouna Sarr, the Brazilian tearful as he left the field on a stretcher.
