However, Stubbs hasn't done any baseball-related activities since Tuesday.
"I still haven't done any activity to test how it feels," Stubbs said. "Yesterday was more of a take it easy, don't aggravate it and get treatment done. I already got some treatment done additionally, today. We'll see what the training staff says and maybe incorporate some movements and see how it feels."
Stubbs said walking around and doing normal things causes him no issues. Taking a swing with a bat could be another story.
"Anything that makes it contract a little bit will make it twinge," he said. "Hopefully it won't be bad enough to keep me out long."
There is no timetable yet for a Stubbs return to the lineup. Chris Heisey started in center field in his place again on Thursday against the Pirates.
