Houck may not be able to pitch in Wednesday's doubleheader against the Twins, as he threw in an alternate-site game against the Mets on Saturday, Alex Speier of The Boston Globe reports.

EDGE Analysis

The doubleheader could potentially have been an opportunity for Houck -- who struck out eight while allowing just two earned runs over five innings in his first start of the season -- to make another start, but the timing doesn't seem to line up. He was optioned to the alternate site last Wednesday, and he can only return within 10 days either as the extra man for a doubleheader or to replace someone else who landed on the injured list. That means he also won't be able to make a spot start Thursday unless someone gets hurt.
