Bour is not in the starting lineup Monday against the Rays, Joe Frisaro of MLB.com reports.
With left-hander Matt Moore taking the mound for Tampa Bay, the Marlins decided it was a good day to give Bour his first day off since May 13. Chris Johnson will slot in at first base in his stead, although Bour will likely return to the lineup Tuesday with right-hander Jake Odorizzi expected to pitch for the Rays.
