Astros ace Dallas Keuchel won't begin throwing again for about a week as he recovers from neck discomfort that has landed him on the DL for the second time this season.

Keuchel was scratched from his start on Wednesday at Kansas City and placed on the 10-day disabled list a day later, a move retroactive to June 5. It's the same problem that put him on the disabled list earlier and caused him to miss one start.

"It's not something that I want to keep reaggravating every time I go out there every five days," Keuchel said.

"I'd rather nip it in the bud right now and make sure it's fully gone than go back out there and enjoy being healthy."
