The next step in recovery is wearing a protective guard on his batting helmet during spring training, according to Joe Fariso of MLB.com.
"There's no concerns on our part," Marlins president of baseball operations Michael Hill said. "We've worked closely with Giancarlo and the helmet manufacturer. He will wear a half-cage to protect the injured area. He's worked out with it."
The outfielder signed a record breaking 13-year, $325-million extension in November. He tested his new gear during the offseason and he may even wear it throughout the season.
"All season I'll wear it, given it is comfortable vision-wise," Stanton said the day he signed. "Just to rule out any type of doubt. We'll see after the first year."
The 25-year-old had a huge season, leading the National League with 37 home runs and owning a 6.1 wins above replacement over 145 games.
