Edmonds had to leave Wednesday's game against Tampa Bay after an at-bat in the fourth inning because of soreness.
"It's been bothering me a couple days on the turf," Edmonds said. "In the first inning, I went back on the fly ball [by Tampa Bay's Eric Hinske] and something popped. My arch is sore. I tried to play a couple extra innings, but better safe than sorry."
Wednesday marked the Cubs' fifth straight game on turf after three games in Toronto over the weekend. The Cubs were already playing short-handed because outfielder Reed Johnson was bothered by back spasms. Johnson was available, but on a limited basis.
"I told you I was a little concerned about the Astroturf two trips in a row -- what are you going to do?" Cubs manager Lou Piniella said.
"He couldn't push off very well," Piniella said of Edmonds. "We took him out for precautionary [reasons]. The last thing we need is to have that thing tear."
Edmonds had gutted it out for a couple more innings and was 0-for-2, striking out in the second and flying out to left in the fourth. He was hitting .231.
"I'm hoping it was just soreness and the scar tissue popped," Edmonds said. "Hopefully, I'll wake up tomorrow morning [after taking] some medication and hopefully quiet it down, and we'll see how it goes."
When the Cubs were in Toronto, Edmonds even tried changing his shoes to alleviate some of the discomfort.
"The last day in Toronto, I played in tennis shoes for a couple innings," he said. "I haven't been on turf for a while, and in cleats, it's a bad combination. I had to do a lot of running in Toronto, so it was a little sore. Tonight, like I said, it popped and got pretty sensitive.
"I'm just going to go day to day right now. Hopefully, getting off the turf and on some grass will ease the pain a little bit."
