Gonzalez tried rest as a cure, but 10 weeks was unable to fix the ligament.
The All-Star outfielder will travel to a hand specialist in Cleveland on Thursday, the Post reported. If the recommendation is to undergo surgery, Gonzalez will have it done within the next two months.
"It's my decision," Gonzalez told the Post. "I am probably going to have it regardless of what he says. It's just not getting any better. I want to be ready for spring training."
