"Right now, he's penciled in for the next game, his next start," said Guillen on Tuesday. "I'm not going to push this kid and say, 'We need you out there for the next start.' He will tell me how he feels."
Guillen decided to skip Floyd's start Monday against the Twins after the right-hander left his latest trip to the mound in Seattle after just three innings. Floyd was bothered by soreness in his left hip, which has hampered him for the past three or four weeks.
If the White Sox were deemed completely out of playoff contention, a state they found themselves pretty close to entering Tuesday's game, then Guillen had talked about shutting down Floyd for the remainder of the season. And that option remained out there Wednesday.
"He's got to be honest with myself, with himself and make sure we trust him," Guillen said. "I'm not going to take any chances [of this kid hurting] himself on the field."
Floyd has posted an 11-11 record this season, with a 4.06 ERA over 30 starts and 193 innings. He has fanned 163 and given up just 178 hits.
But when asked about the affected area Wednesday, Floyd didn't express a huge level of improvement.
"I wasn't even stepping and throwing and I felt it a little bit," said Floyd, as to how the area felt when he simply was playing catch. "The aching from my last start has pretty much diminished. The deep down stuff still feels like it's there.
"We just have to keep on monitoring it and see how I feel. I still do certain movements and still feel it there, with the same amount of intenseness. I just take it day by day and keep getting treatment."
In the meanwhile, Guillen spoke of concern regarding how this injury could impact the 26-year-old and White Sox rotation staple in the future.
"If this is happening right now, I don't know what's going to happen next year," Guillen said. "Maybe he's got to change his delivery. Or we have to come up with something different.
"We've got to come up with another program. We've got to do something about it, because this thing has been bothering him for a little while. I don't know if it's just the way he throws the ball, or the way he lands. He's got so many things about it. We have to do something about that situation."
