Edwards was removed from Friday's game against the Cubs due to lower-back discomfort, Daniel Alvarez-Montes of ElExtraBase.com reports.
Edwards singled during his lone at-bat Friday and then stole second base, but he was replaced at shortstop once the Marlins took the field in the third inning. The severity of his back injury remains unknown, though Vidal Brujan would presumably take over as Miami's starting shortstop if Edwards is unable to play Saturday.
