Stanton was carted off the field and sustained facial lacerations requiring stitches, multiple facial fractures and dental damage after being hit by an 88 mph fastball from Brewers pitcher Mike Fiers.
Following the game, the Marlins had said Stanton would likely be done for the season.
On Tuesday, Stanton posted a photo on Instagram showing his recovery from the injuries.
Stanton was SI.com writer Cliff Corcoran's frontrunner for NL MVP before the injury. He hit .288 with 37 home runs and 105 RBI in 2014 and currently has a National League-leading .555 slugging percentage.
