The Spurs' worst fear has become a reality.

Veteran point guard Tony Parker suffered a ruptured left quadriceps tendon in Wednesday's Western Conference semifinal game against the Rockets, the team announced Thursday. He will miss the rest of the playoffs and a timeline for his return will be announced later.

Parker had to be carried off the court after he went down with 8:52 remaining in the fourth quarter of San Antonio's win. He attempted a running jumper in the lane, but his left leg buckled as he landed on the court at AT&T Center. The 34-year-old remained on the floor as action transitioned to the other end of the court following his miss. 

Parker tried to massage the pain out himself as he tried to walk off the floor, but could not put any pressure on his left leg and was carried off the court by teammates.

"It's not good," Spurs coach Gregg Popovich said after the game. 

Parker was averaging 15.9 points and 3.1 assists this postseason.
