PHILADELPHIA -- Jimmy Rollins is eligible to come off the disabled list in time for Monday's game in Arizona.

That time frame may now be in question.

Rollins continues to run and field grounders before games, but apparently has had some discomfort running the bases on his sprained left ankle.

"I heard that [Tuesday] when he made turns, he kind of felt it," manager Charlie Manuel said. "In the field, he said it felt pretty good. [Head athletic trainer] Scott Sheridan said he felt it when he made turns on the bases."

Rollins had never been placed on the DL before this season, and the Phillies don't want to take any chances.

"I need to see how he feels and if he's 100 percent ready to go," Manuel said. "If we see that, I'll be comfortable and than he'll be comfortable. This is the first time he's been hurt, and I think it's important when he comes back that he's free to play like he used to."

Manuel wants Rollins to play in at least four or five Minor League rehab games -- though none have been scheduled yet -- before rejoining the Phillies.

"I'd like to see him play back-to-back," Manuel said.

In the meantime, the Phillies must wait for the reigning NL Most Valuable Player to get healthy.

"It's feeling better," Rollins said as he walked by toward the batting cage.

But while the injury lingers, Manuel keeps wondering when Rollins will be back.

"Yeah, I'm definitely concerned about it, of course," Manuel said.
