"If we had a one-game lead, I'd be really pressing the issue," Dunn said. "I want to wait until I have no problems as opposed to coming back a day or two early and having this thing do this again and missing significant time.
"It's one of those things where I don't know what else to do other than time and treatment. I think we gave it a lot of time, so hopefully it's ready."
Dunn said that he received a pain-killing injection along with going through daily treatment.
"What we're trying to do is get it to where I can swing, that's the problem," Dunn said. "It's not getting out of bed now, it's not sneezing. I'm not going to pick up a bat today and hopefully tomorrow they'll let me do some stuff."
"We're being cautious with it," White Sox manager Robin Ventura said. "He wanted to play yesterday, too, so I don't necessarily go by what he's saying."
