Rockies trainer Keith Dugger told the Denver Post that "everything went perfect" with the surgery on Monday, but Gonzalez's rehab will take months. The outfielder will be in a walking brace for three weeks and will have limited mobility.
"We really don't know how he's going to be until that 4½- to five-month mark," Dugger told the Post. "He might be a little delayed in spring training. But our goal is to get him there and get him ready."
It was the third surgery of the year for Gonzalez, who was shut down for the season last week after going on the disabled list with not only an aching left knee but a sprained right ankle. He was out earlier this season after doctors removed a small tumor in his left index finger. he also had his appendix removed in January.
Gonzalez struggled at the plate, hitting .238 with 11 homers and 38 RBIs.
