"Braves left fielder Martin Prado said Sunday he needed a couple more days before he'll be ready to start a minor league rehabilitation assignment in his return from staph infection surgery.

Prado said the wound on his right calf still hasn't closed yet. "It's almost closed," he said.

The Braves had hoped Prado might be able to head out on assignment as early as Monday, play four games, and be ready to come off the disabled list for the weekend series in Philadelphia before the All-Star break. That looks less likely at this point.

Prado needs the wound to heal completely before he can play. He's been taking batting practice since Friday without incident and said it was a matter of getting his legs back in shape.

"I feel OK," Prado said. "Not to perform at 100 percent yet."

Chipper Jones planned to receive a cortisone injection in his sore right knee after Sunday's game against Baltimore in hopes it will give him some of the same relief he had after the last injection six weeks ago."
