ATLANTA -- The Phillies could have used Brett Myers this weekend at Turner Field.

But Myers never pitched, despite the fact the bullpen pitched 16 innings in the three-game series. In fact, Myers has not pitched since Sept. 12 against the Mets at Citizens Bank Park. Myers said Friday he had not thrown because Phillies starters had been going deep into games. But that no longer held true after J.A. Happ pitched three innings Friday, Pedro Martinez pitched three innings Saturday and Cliff Lee pitched four innings Sunday.

Phillies general manger Ruben Amaro Jr. said following Sunday's 4-2 victory over the Braves that Myers has had soreness in the back of his right shoulder for more than a week. Myers will fly to Philadelphia on Tuesday to see team physician Michael Ciccotti to "see if there's anything very serious about it."

Myers, reached by telephone Sunday night, said, "I don't think it's real serious. I have some stiffness and tightness, and they want me to go get it checked out."

The Phillies have just 14 games to play before the postseason, and with left-handers Scott Eyre (loose body in his left elbow), J.C. Romero (strained left forearm) and Jack Taschner (strained back), and right-hander Chan Ho Park (strained right hamstring) sidelined with injuries, this comes at a bad time.

But Myers, who missed more than two months in 2007 with a strained right shoulder, sounded optimistic he would be pitching before the end of the regular season. He said he has thrown each of the previous four days and has felt better each time.

"I should be back," Myers said.

But there remains reason to be concerned. Myers is flying to Philadelphia to get examined.

"They're saying it's a possible strain," Amaro said.

Myers pitched five times in eight games upon his return from the disabled list, where he spent much of the season recovering from surgery on his right hip. Myers said he wanted the ball in those situations, and would not say if that work played a role in the soreness.

"I don't think he came back too quick," Amaro said. "I think it was just probably the change of role and pitching a lot."

Amaro is hopeful Eyre and Romero will be back soon. Romero is in the instructional league in Clearwater, Fla. The Phils hope to have him face hitters this week. Eyre could throw another bullpen session Tuesday.

Amaro said Park has improved and added that there is a chance the veteran righty could pitch before the end of the regular season.
