Doyle (oblique/groin) is expected to resume his rehab assignment at Triple-A Albuquerque on Friday, Thomas Harding of MLB.com reports.
Doyle landed on the 10-day injured list back in late May because of a left oblique contusion, but it's groin tightness that's held him out of action since Sunday. As long as he doesn't encounter another setback, Doyle still has a good chance to return to the Rockies' active roster before the All-Star break.
