Olson (shoulder) could be lined up to be activated from the 15-day injured list to start Monday against the Royals, Evan Woodbery of MLive.com reports.
Prior reports had suggested that the 25-year-old was trending toward a return early this week in Kansas City, and Casey Mize and Tarik Skubal have been named the probable starters for Tuesday's and Wednesday's contests, respectively. Detroit hasn't officially announced a starter for Monday, but Olson appears primed to make his return after missing nearly two months due to a shoulder strain. He made a pair of rehab starts and most recently tossed three shutout innings on 45 pitches for Triple-A Toledo this past Tuesday, so Olson could be somewhat limited from a workload perspective if he toes the rubber for Detroit on Monday.
