Garza, who came out of last Saturday's game with cramping in his right elbow, will not start until late next week, Cubs manager Dale Sveum said Friday.
The right-hander underwent an MRI on his elbow this week, which showed evidence of the cramping but was otherwise clean.
"We'll just wait and see what happens with his throwing program, and [he could start], possibly, maybe late next week," Sveum said.
Even though he's sidelined now, Garza could still be traded. It's up to the other team as to whether they want to take that risk. Did Sveum expect Garza to be dealt?
"I don't expect anybody to be gone until it happens anyways," Sveum said. "I'm not dwelling on that. We have to get him back on the mound."
The Cubs have yet to name a starter for Monday in the upcoming series against the Pirates, although Justin Germano could get the call if he's not needed this weekend. Ryan Dempster will start Tuesday and Travis Wood on Wednesday.
