"I'm going to try," Correia said. "They're not real sure, but I'm going to do everything I can to try to get back."
Correia injured the muscle during his last start, Friday against the Reds. He said he noticed it while at bat in the bottom of the fourth inning. He allowed four runs in the fifth inning and stayed in the game through the sixth.
"I just went back out for the fifth and knew I'd strained it," he said. "I managed to pitch a couple more innings after that. Not very pretty innings."
Correia was sidelined by a strained oblique in 2008 and missed all of May and half of June -- "a good chunk of the season," he said. But he said this injury was not nearly as bad.
He said he only feels the pain when he throws, meaning he cannot play catch for the time being.
"We'll test it at some point here, see if I can throw," he said. "I've pretty much got one more chance. If I can throw in a couple weeks, then I'll be able to make it back. If I'm not able to play catch then, it'll be too late."
