"He's clear, it was clear," manager Ned Yost said. "So it's the stress reaction -- I don't know all these scientific words, for me it's a bone bruise. There's not a stress fracture there, which is good news because that would've taken longer, so this is going to be a lot quicker process."
Yost said that Holland will be shut down for five days, then go back on a throwing program, but it might be three weeks before he can get back to pitching.
Holland was placed on the 15-day disabled list on Saturday after an MRI revealed the rib stress reaction.
