The Houston Astros have placed Dallas Keuchel back on the disabled list with neck discomfort.

Keuchel was scratched from Wednesday's start against the Kansas City Royals with what the club initially called an illness.

"He's going on the DL for a minimum of 10 days," A.J. Hinch said. "That brings concern in its own right. Being symptomatic with the same injury from earlier in the year is concerning, but until we see him and talk with him, and get another report from the doctor, we just won't know.

"I'm not sure what goes into these pinched nerves, or what the doctors' plan will be to get him better. We need to get him right and back on the mound, we hope soon. If he misses one start, great. If it's more than that then it is what it is."

He is 9-0 with a 1.67 ERA in 11 starts this season.
