Ryan (illness) will start Tuesday or Wednesday against the Mariners, Do-Hyoung Park of MLB.com reports.
Ryan began a rehab assignment at Triple-A St. Paul on Thursday and allowed a hit and no walks while striking out four in three scoreless innings. The Twins haven't yet settled on a date for him to rejoin the starting rotation, but he'll pitch sometime during a road trip to Seattle next week. The right-hander posted a 2.63 ERA and 1.06 WHIP in 27.1 innings over his five starts prior to his absence.
