Davis chased and dived as he attempted to catch Tommy Edman's deep drive to lead off the fifth inning. Davis briefly had the ball in his glove but lost possession as he rolled on the warning track and immediately started favoring his knee.
The 31-year-old Davis, acquired from Detroit on May 22, figured to get extended time in center field after starter Jazz Chisholm Jr. was placed on the injured list Monday because of a left oblique strain. Davis also stepped in for Chisholm while he was sidelined with a turf toe injury last month.
The Marlins said an MRI revealed Chisholm's strain was minor. There is no timetable on his return.
