Sweeney hasn't played since leaving early from Monday's 5-3 win over the Marlins. Iglesias was scratched from a "B" game Sunday morning because of his strained groin, which had been nagging him for almost a week.
"[We will] just kind of see how it goes," Sweeney said Thursday morning. "I think tomorrow I'll probably start hitting again, and then as far as a timetable for running, I don't know. [We will] just kind of see how it is and kind of get that muscle spasm out of there, stuff like that."
Sweeney said his legs were sore for a couple of days before Monday, and he first felt a spasm in the field and then a twinge on a check swing. Sweeney didn't try to take himself out of the game, but he did tell the team he wouldn't be able to run well, and the Sox pulled him out of the game.
"Iglesias probably could have played today. Sweeney couldn't. Sweeney thinks he's probably another day away," manager Bobby Valentine said. "Iglesias, we were here [at the training complex during Wednesday's off-day], [and] he felt good yesterday. I told him we were going to give him one more day, just to be sure."
Catcher Jarrod Saltalamacchia was not in Thursday's lineup at home against the Cardinals because he has "a little hip situation," Valentine said, and he wanted to rest Saltalamacchia ahead of Saturday's split-squad action. Half of the team will travel to Sarasota to play the Orioles, while the other half will remain at JetBlue Park to face Baltimore's split squad.
Valentine isn't pleased Boston plays at home Friday night and then has two games Saturday.
"It's cruel and unjust punishment, but we had an off-day yesterday, so we'll be ready," said Valentine. "With that, [Saltalamacchia is] probably going to have to play two days in a row somehow, so we're resting him today."
