BALTIMORE -- Dustin Pedroia on Thursday refuted a report that he would undergo surgery Friday to place a screw in his previously fractured left foot. But the Red Sox second baseman sounded resigned to the probability that the procedure would be the best way to ensure that the lingering injury gets an opportunity to fully heal.

"I think that putting the screw in is probably the best idea," Pedroia said. "It's a 90 percent chance that I heal, that that bone heals. I don't want to get January and go through my workouts and not feel good and then I miss some of next year. None of us want that to happen. So I think putting the screw in is probably the best idea. I'll find out tomorrow."

Pedroia will undergo a CT scan early Friday morning, with the results determining if surgery is necessary.

"If I have to have surgery, we'll do it later in the day," he said.

Pedroia, who is hitting .288 with 12 home runs and 41 RBIs, has been on the 15-day disabled list since Aug. 20, retroactive to Aug. 19, with soreness in his left foot. That's the same extremity that was fractured earlier in the season, forcing him to the DL from July 26-Aug. 17. He's missed 44 games and the Red Sox are 23-21 in his absence.

He was examined in Baltimore on Wednesday by Dr. George Theodore, a team foot specialist who saw him while on a family vacation that coincided with Boston's series at Camden Yards. Red Sox manager Terry Francona said after Wednesday's game that he was encouraged by the results of the exam.

The next step is Friday's CT scan, but Pedroia insisted that no determination had been made regarding the need for surgery.

"I don't know [anything]. I woke up today and heard our team sources said I need surgery, so I guess I'm going to have it," he said sarcastically. "I don't know what ... [is] going on, to be honest with you."

One key in the decision-making process will be whether rest and rehabilitation -- Pedroia has been in a walking cast occasionally while with the team in Baltimore -- has accomplished enough to heal the problem.

Pedroia doesn't want a repeat of what's already happened -- a premature return from the disabled list only to land right back on the bench because the injury wasn't fully healed.

"I think [surgery] would make it heal more. They said there's like a 50 percent chance that [without surgery] I could feel better and still, like what happened last time - I played two games and not be able to walk the next day," Pedroia said. "Putting the screw in would help it heal, so there's a good chance I'll have the surgery at some point."

Speaking with reporters during his daily media session Thursday, Francona shied away from the previous night's optimism.

"Whatever [Pedroia] wants to say is up to him. I'm kind of stuck. What I said is what I'm able to do. ... Petey already yelled at me for saying too much and I don't think I said anything," Francona said.
