Pau Gasol iffy for Sunday's Game 4

CHICAGO -- Pau Gasol has a strained left hamstring and will undergo an MRI on Saturday.

The Chicago Bulls center is unsure if he will be able to play Sunday in Game 4 of the Eastern Conference semifinals against the Cleveland Cavaliers.

Gasol, who played just 22 minutes and scored six points in the Bulls' 99-96 win Friday night, said he initially injured the hamstring in Game 2 and then felt it tighten up again in the first half of Game 3.

"[The hamstring is] sore. It tightened up already in Game 2," he said. "Today, it started off well, but a couple minutes into the game, it started tightening up again. I just tried to play through it as much as I could, but in the second half, third quarter it got worse, so I couldn't sprint. I definitely couldn't sprint. We got to a point where I couldn't really run well, either. So just had to get out of the game, and we'll evaluate it tomorrow."

The Bulls training staff tried to stretch Gasol out on the bench during the game, but that didn't seem to help. Gasol received additional treatment after the game and will continue to ice the hamstring heading into Saturday.

"You never know. I'll find out more about it [Saturday] when we do a couple tests and see the extent of the injury," he said. "We're going to keep icing it tonight. Hamstrings are tricky. I've had a couple tears in the past, and it's no joke."

The Bulls lead the series with the Cavaliers 2-1.
