Cueto (elbow) is planning to throw a bullpen session this weekend, Kerry Crowley of The San Jose Mercury News reports.
Cueto was on the verge of joining the Giants' rotation, but he felt soreness in his upper back during his final rehab start and in a Tuesday bullpen session, so he will remain on the recovery track for now. Manager Bruce Bochy said Wednesday that Cueto could start during next week's homestand if his bullpen session goes well.
