"We'll see how it feels after Saturday," Kelley said. "If I need another one, then we'll do it. If I feel fine and my stuff's there, that might be the only one. I feel normal. I feel like I did before my back hurt."
Kelley has not pitched in a big league game since May 6 in Anaheim due to a strained lumbar spine. He is 1-2 with a 3.52 ERA in 16 appearances this season.
