Houser will no longer start Wednesday in Philadelphia after warming up in the bullpen during Tuesday's game versus the Phillies, Abbey Mastracco of the New York Daily News reports.
Houser had been set to rejoin the rotation after a brief demotion to the bullpen, but the club had him get loose when it looked like he might be needed in relief Tuesday. He ultimately didn't pitch, but he won't be ready to start Wednesday. The team has not yet announced a starter for Wednesday's contest.
