"Homer is not pitching. He came out a little more sore than normal," Reds manager Dusty Baker said. "We kind of anticipated that a little bit. We decided to scratch him and wait a little more."
Bailey has been on the disabled list since May 24 with right shoulder inflammation. He was scheduled to be examined by team medical director Dr. Tim Kremchek on Friday.
"I threw the other day and felt great," Bailey said. "The last couple of days, there's been some soreness in places where I usually don't get soreness. We'll evaluate and go from there. I'll know more later once I see Kremchek."
Bailey said he felt the soreness after throwing on flat ground.
The right-hander pitched for Triple-A Louisville in a rehab start on Tuesday and threw 86 pitches, allowing five earned runs in 4 1/3 innings. He was scheduled to throw in a bullpen session Friday but was scratched from that and will not make another rehab start this weekend.
"If it was anything seriously wrong, I would have felt it then [Tuesday]," Bailey said. "I didn't feel it then. We're trying to take it slow because we can nip it in the bud now or we can maybe suffer later."
In three starts for the Reds, LeCure has gone 1-2 with a 3.12 ERA. He will face 2009 American League Cy Young Award winner Zack Greinke of Kansas City (1-8, 4.05 ERA).
