Peavy experienced more back tightness after his rehab start with Triple-A Sacramento on Wednesday, Amy Gutierrez of CSN Bay Area reports. The right-hander's rehab will be put on hold for the moment, with manager Bruce Bochy saying the team will slow play it with him. Peavy will see a doctor Friday to determine the true extent of the setback.

Peavy (back) will make at least two more rehab starts, John Shea of the San Francisco Chronicle reports. Peavy struggled in his second rehab outing, allowing six runs over 4.2 innings for Triple-A Sacramento on Wednesday. He was previously expected to make just one or two more rehab appearances after Wednesday's, but manager Bruce Bochy is now saying that the right-hander will have at least two more outings in the minors. Peavy is thus unlikely to return until the second or third week of June.

Peavy (back) is scheduled to make a rehab start for Triple-A Sacramento on Wednesday, CSN Bay Area's Alex Pavlovic reports. It was previously reported that Peavy may only need two or three rehab outings, and Wednesday's start will mark his second of the assignment. He thus seems to be on track to join the Giants in early June.

Peavy (back) is scheduled to throw 50 pitches in his rehab start Friday, and may only need two or three starts before rejoining the big league team, John Shea of the San Francisco Chronicle reports. Peavy is slated to be re-evaluated following his first rehab appearance Friday, but if all goes according to plan he'll pitch again Wednesday and then could return to the majors shortly after that. Barring a setback, the righty seems to be on track for a late-May or early-June return.

Peavy (back) will begin his rehab assignment Friday at Single-A San Jose, Amy Gutierrez of CSN Bay Area reports. Gutierrez noted that Peavy will be re-evaluated following his outing to determine the next step of his assignment. Given that he has thrown multiple bullpen sessions with no setbacks, he could be back with the Giants by the end of May if he progresses well through his rehab assignment.

Peavy (back) looked fine after a bullpen session Tuesday, and the Giants are looking for him to pitch in a rehab game in San Jose on Friday, depending on how his back and hip feel, Henry Schulman of the San Francisco Chronicle reports. With Peavy emerging from the bullpen session without any noticeable issues, the next step in his recovery process will be his rehab start. If that goes well, Peavy could be well on his way to returning on schedule at the end of May.

Peavy (back) threw 50 pitches in a bullpen session Tuesday and is slated to throw another bullpen session Thursday, Andrew Baggarly of the San Jose Mercury News reports. The next step in Peavy's recovery will facing live batters in extended spring training. He threw his first bullpen Friday since landing on the DL and has not reported any setbacks. If all goes well at extended spring training, the next step for Peavy will be a rehab assignment.

Peavy (back) will work at the team's spring training facility to rehab while the team is on the road and hopes to face hitters in a simulated game, the San Francisco Chronicle's Henry Schulman reports. He threw 40 pitches off the mound Friday and felt good then and Saturday during his recovery day. While Peavy is not yet ready for a rehab assignment, he seems to be making solid progress lately and could still rejoin the Giants' rotation in late-May/early-June.

Peavy (back) will throw a bullpen session Friday, John Shea of the San Francisco Chronicle reports. Peavy resumed throwing off a mound Saturday for the first time since landing on the disabled list, and it appears he may be nearing a rehab assignment. The team will monitor how he feels after the bullpen session and then reach a decision on the next step afterward.

Peavy (back) threw off a mound Saturday for the first time since landing on the DL, John Shea of the San Francisco Chronicle reports. The session consisted of 20-25 fastballs at about 70-80 percent, and Peavy reported improvement with his condition afterward. Peavy had been limited to long toss after an MRI revealed a muscle strain and continued issues with the SI joint in his lower back in mid-April. It will be hard to know exactly where Peavy stands until he's throwing at maximum effort.
