NBA: Parker faces season-ending surgery - reports

San Antonio Spurs star Tony Parker faces season-ending surgery after being carried off during his team's NBA playoff win over the Houston Rockets, multiple US media reports said Thursday.

Parker collapsed to the court in agony during the fourth quarter of the Spurs' series-levelling win over the Rockets on Wednesday.

The French star was carted off by teammates Dewayne Dedmon and Dejounte Murray and did not look up as the crowd chanted his name.

Several reports said Parker, 34, had undergone a scan which revealed an injury to a quadriceps tendon requiring surgery.

San Antonio coach Gregg Popovich gave a grim assessment of Parker's injury following his team's win.

"It's not good," Popovich said of Parker, who scored 18 points in the win.

Team-mate Manu Ginobili said on Wednesday Parker had been unable to place any weight on his injured left leg.

"It's hard to see him limping and hurting now, and you kind of know we're not going to see him any time soon," Ginobili said. "That's a tough blow."

Parker is in his 16th season in the NBA and has helped the Spurs to four NBA titles in the past. The veteran missed 16 games in the regular season and San Antonio went 12-4.
