KANSAS CITY -- Jake Peavy didn't feel good playing catch on Saturday, and it's unlikely the right-hander will start on Monday against Kansas City as originally planned.
"Still grabbing me pretty good throwing the ball. I was able to throw but it was still grabbing me to the point where playing catch is a problem," Peavy said of his balky back. "If that's a problem, certainly throwing 100 percent off the mound is going to be. Hopefully tomorrow, with the treatment during the game today, afterwards seeing a chiropractor seeing a massage therapist at the hotel we can get it knocked out. Certainly don't want to be on the DL or be out longer than I have been."
Chris Sale or Hector Santiago will start Monday's game, although no decision has been made yet. Earlier Saturday, Peavy was encouraged by his progress after suffering back spasms earlier in the week, causing him to miss his scheduled start Thursday in Texas.
"The other day it was impossible to pitch," Peavy said before playing catch Saturday. "I could hardly move. It’s still tight but way better. My range of motion, I can walk around without any kind of discomfort. It’s something that’s manageable and I hope to keep that."
Peavy had hoped to push through the discomfort on Monday, and added he doesn't think doing so would cause any serious structural damage and lead to a significant injury.
More from the sick bay
Manager Robin Ventura said left fielder Dayan Viciedo looked good swinging a bat on Friday, and if all goes well could be sent out for a minor league rehab assignment in the next few days.
Outfielder Jordan Danks was available for Saturday's game, but didn't play. He's been out of commission since last Friday, when he suffered a knee contusion running into a wall at U.S. Cellular Field.
As for John Danks, the left-hander said Friday he thinks he only needs one or two more rehab starts before he's ready to return to the White Sox. Ventura, though, tempered that enthusiasm a bit on Saturday.
"I know he's got at least two, there's the possibility of at least three (rehab starts)," Ventura said. "But the reports are good, they're getting better, it's just when everybody feels he's ready because I don't get to see him. You have to take the word of people who are seeing him, how he's feeling, how that's going. We'll be looking forward to having him."
