Los Angeles Angels star Mike Trout will not be returning when he's eligible to come off the injured list on Monday.
Trout, dealing with left rib cage inflammation, hasn't played since July 12. He was a late scratch from the lineup in the Angels' 7-1 loss to the Los Angeles Dodgers last week before the All-Star break.
Head athletic trainer Mike Frostad told reporters on Saturday that Trout had a cortisone injection in his back on Thursday.
"The injection was done into the joint where the rib meets up with the spine," Frostad said.
