Tony Parker (hamstring) uncertain

SAN ANTONIO -- San Antonio Spurs guard Tony Parker will have an MRI of his right hamstring Wednesday and said he doesn't yet know his status for Game 4 of the NBA Finals on Thursday.

Parker went to the locker room with 5:07 remaining in the third quarter of San Antonio's 113-77 win over the Miami Heat on Tuesday night to get his hamstring examined. He returned briefly in the fourth quarter, but with the Spurs holding a big lead, there was no reason to take any chances with an injury Parker described as "weird."

Parker said he couldn't remember any specific play on which he injured himself, but the "weird feeling" got progressively worse in the third quarter and he decided to come out of the game.

"We'll see," Parker said. "We'll get an MRI tomorrow, and hopefully it's nothing big and it's just a hamstring that got tight on me."

Asked whether he thought he'd be able to play in Game 4, Parker said he really wouldn't know until the results of the MRI came back.

Parker and teammate Tim Duncan didn't arrive at the AT&T Center until less than an hour before tipoff due to unusually heavy traffic in the area stemming from a graduation ceremony nearby and rain.

"Oh man, the worst ever in 12 years," Parker said of the traffic near the arena. "I left like an hour and a half before, and it took me two hours to come here. It was a long drive here. The game started at 8 p.m., and I got here at like 7:05.

"Traffic was unbelievable. I've never seen it like that."

When asked whether the disruption to his normal pregame routine could have affected his hamstring, Parker shook his head and said, "I'm not going to say it's like that."

He finished with six points, eight assists and two rebounds in 27 minutes of play Tuesday.
