Stanton had an MRI Saturday morning after complaining of discomfort in the shoulder and missing Friday night's game against the Phillies. The test showed no structural damage and he's day to day.
The Marlins are off to a 1-9 start.
"It's the best possible news," Miami manager Mike Redmond said. "Obviously, you have someone like him out and it's tough. The other guys just have to step up."
Stanton is off to a terrible start. He is hitting .167 without an RBI. He thinks he was hurt trying for a diving catch in the fourth inning of a game April 6 game at the New York Mets.
Also, center fielder Justin Ruggiano is a late scratch from Saturday's game because of right groin tightness.
