Gonzalez underwent shoulder surgery Wednesday and will be out for 9-to-12 months.

EDGE Analysis

Doctors performed a labral repair and debridement on Gonzalez's injured right shoulder. The recovery timeline means he'll miss at least all of next year's spring training and could miss up to half the year.

Gonzalez (shoulder) returned to his rehabilitation assignment at Triple-A Charlotte after having a setback earlier this week, Phil Thompson of the Chicago Tribune reports.

EDGE Analysis

Gonzalez felt some discomfort in his shoulder after throwing a side session. It's not clear when he's expected to make his next rehab start.

Gonzalez has been experiencing discomfort in his injured shoulder, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

Gonzalez hasn't pitched since mid-April while dealing with rotator cuff inflammation. He appeared to be nearing a return after throwing three innings in a rehab start Sunday but will now likely be delayed. It's not yet clear how significant the setback is.

Gonzalez (shoulder) allowed one hit and one walk while striking out one over three innings for Triple-A Charlotte on Sunday.

EDGE Analysis

Gonzalez tossed 37 pitches (26 strikes) in his first rehabilitation assignment. The 34-year-old right-hander is expected to make another two or three starts while rehabbing with the Knights.

Gonzalez (shoulder) expects to make three or four starts while on rehabilitation assignment with a priority to fine-tune his curveball, Tom Musick of the Chicago Sun-Times reports.

EDGE Analysis

Gonzalez, who hasn't pitched in a game environment since April 17, will throw about 45 pitches during his first rehab start Sunday for Triple-A Charlotte. He made particular note of his curveball, for which he says he's developed a feel. "I'm definitely going to be throwing it down there more than any of my other pitches just because that's a big difference from my curveball to my fastball. That's, like, a 20 mph difference, and that's where you want to be. That's a key pitch for me.'' It's hard to see Gonzalez being anything more than a temporary member of the White Sox's rotation. Expect him to get healthy enough to make a few starts before Chicago sends him to a playoff contending team.

Gonzalez (shoulder) will start a rehab assignment with Triple-A Charlotte on Sunday.

EDGE Analysis

Gonzalez recently threw a pair of simulated games and is set to pitch around three innings during his upcoming minor-league outing. The right-hander is expected to require a couple rehab games, as the White Sox will likely have him stretch his arm back out before returning to the fold in Chicago.

Gonzalez (shoulder) threw a two-inning, 30-pitch simulated game Tuesday, Colleen Kane of the Chicago Tribune reports.

EDGE Analysis

Gonzalez will be reassessed Wednesday to determine if he's close to starting a rehabilitation assignment.

Gonzalez (shoulder) threw 25 pitches in a simulated game Saturday.

EDGE Analysis

Gonzalez will have another simulated game and a bullpen session next week. He's expected to begin a rehab assignment as soon as the following Sunday. Given the length of his absence, which has lasted since late April, the veteran could need multiple rehab starts, which would put his return sometime in early July.

Gonzalez (shoulder) completed a bullpen session Sunday, Scott Merkin of MLB.com reports.

EDGE Analysis

It was the second time Gonzalez had thrown off a mound before landing on the disabled list in late April with right rotator cuff inflammation. Gonzalez indicated that he felt good during the session, so he could be cleared to face hitters in live batting practice during the upcoming days. A minor-league rehab assignment would then follow, but it seems unlikely that Gonzalez would be ready to return from the DL before late June at the earliest.

Gonzalez (shoulder) played catch Wednesday and Thursday, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

Gonzalez is slowly working his way back from inflammation in his right shoulder and hopes to begin throwing next week after he was shut down from such activity for 10-to-14 days. "I think I can pitch after this long rest,'' he said. "I want to be out there [at the end of June] and help out.'' By then, the White Sox should get Carlos Rodon (shoulder) back in the rotation and there may not be a spot available for Gonzalez.
