Whether Parker gets to play for the Spurs in Game 4 is up in the air.
"We'll see," Parker said. "I felt something on my hamstring so I don't know, I have no idea when it happened."
After the third-quarter injury, Parker had to head to the locker room. He spent much of the fourth quarter on the bench before returning for just two minutes of play.
Parker suffered a bruised left calf earlier this season but returned to play after a precautionary MRI. He took the Spurs over the Heat in a Game 1 buzzer-beater. If he is unable to return, the Spurs are likely to start Cory Joseph.
Game 4 is on Thursday in the Spurs' home San Antonio.
