With a commanding seven-run lead, Stanton was replaced in right field by Chris Coghlan in the seventh. The Marlins don't believe the twisted ankle is serious, but Stanton may sit out Monday's 2:20 p.m. ET start against the Cubs at Wrigley Field.
"Working against me is it's a day game," Stanton said. "We'll see in the morning."
Stanton, batting .248, leads the Marlins in homers with 18 and is tied with Justin Ruggiano for the club lead in RBIs with 42.
If Stanton is given a day off, Coghlan and Ruggiano are options to play right field. But Ruggiano was given Sunday off because of a sore calf.
"We'll see how Stanton feels tomorrow," manager Mike Redmond said.
