Quintana (ribs) hopes to be cleared to play catch at his six-week follow-up doctor's appointment Friday, Anthony DiComo of MLB.com reports.
It would be the first time Quintana has done any throwing since he had surgery in mid-March to repair a stress fracture on the left side of his rib cage. He'll need to be built back up deliberately, with a return sometime in July looking like the best-case scenario.
