"Right-hander Ricky Nolasco will miss the final month of the season due to the meniscus he tore last month.

Scheduled to start Friday against the Braves, Nolasco said after Wednesday's game he will undergo right knee surgery to repair the problem next week.

"It's just not letting me do what I want to do," Nolasco said. "I can't squat all the way down, just little things like that…People have been telling me I have to be smart and I'm not going to risk hurting something else trying to compensate."

Manager Edwin Rodriguez said left-hander Andrew Miller likely will take Nolasco's place.

Nolasco already had missed one start after being diagnosed with the meniscus tear. He came back to pitch Saturday in Atlanta and lasted just two innings, allowing six runs on seven hits. Afterward, Nolasco said the knee was fine. Rodriguez removed him because Nolasco needed 41 pitches to get through the second and he had not pitched in 11 days.

Nolasco since then told friends he didn't feel all that comfortable on the mound Saturday. Missing the final month will afford Nolasco the chance to have surgery to repair the meniscus sooner rather than later. He's looking at about a four-week recovery process.

Nolasco's season ends with a 14-9 record, 4.51 ERA, 33 walks and 147 strikeouts in 157 2/3 innings (26 starts).

Hayes suffers separated shoulder

The home plate collision with Niger Morgan in the 10th inning Tuesday likely will cost Brett Hayes the remainder of the season. Wednesday, Hayes was diagnosed with a grade one left shoulder separation. Grade one indicates he did not tear any connective tissue."
