PARIS (AP)—Neymar went off on a stretcher after twisting his right ankle late in league leader Paris Saint-Germain's 3-0 home win against third-place Marseille on Sunday.
The Brazil striker was taken off with 10 minutes remaining, after going in for a challenge on Marseille defender Bouna Sarr near the halfway line.
The match between the traditional rivals became increasingly heated, especially in the second half, with cheap challenges from both teams and 11 yellow cards - six of them for PSG. Neymar had his head in his hands and appeared tearful as he was taken off. His standing leg jarred as he lost balance and the weight of his body went onto his ankle, which briefly buckled under him.
The win moved PSG 14 points clear of second-place Monaco, with only 11 games left, but thoughts were with Neymar.
''We were solid and we tried to control the game,'' PSG captain Thiago Silva said. ''It's a shame that we lost an important player at the end.''
Asked if he thinks Neymar's injury is serious, Silva speculated that it was, saying: ''Yes, because it was swollen straight away. I'm not a doctor but I don't think he'll be ready for Wednesday (in the French Cup against Marseille).''
PSG's first two goals stemmed from Marseille's mistakes at the back.
In the 10th minute, PSG right back Dani Alves' pass behind the defense was easily read by left back Jordan Amavi. But rather than clearing the ball properly, his soft sliding tackle knocked it to Kylian Mbappe, who skipped past another defender before drilling a low shot into the bottom right corner.
The second goal came from the other side, as midfielder Adrien Rabiot broke down the left and his cross found Neymar, whose side-footed pass was turned into his own net by center half Jorge Rolando in the 28th.
PSG's third in the 56th owed nothing to fortune, as Cavani expertly controlled Neymar's pass from the left with the inside of his foot, easily turned Rolando and smacked in a powerful shot past goalkeeper Yohann Pele for his league-leading 24th of the season.
Mbappe shook his head disapprovingly when substituted, with winger Angel Di Maria replacing him for the last 30 minutes.
Marseille threatened mainly from midfielder Dimitri Payet's laser-like free kicks, but no one could get on the end of them. The defeat means Marseille stays two points behind Monaco.
