Donovan (groin) will shift his rehab assignment to Triple-A Tacoma on Friday, Shannon Drayer of SeattleSports.com reports.
Donovan was cleared to embark on a rehab assignment Wednesday in the Arizona Complex League. He'll take the next step in his recovery by playing in Triple-A, but given that he's been sidelined for nearly two months, Donovan will likely need to play in several more minor-league games before returning to the majors.
