Ryan (groin) will begin a rehab assignment with Triple-A St. Paul on Friday, Darren Wolfson of Channel 5 Saint Paul reports.
Ryan tossed a bullpen session Tuesday and came out of it with no concerns, clearing the way for his return to game action. It's not clear how long a rehab stint he will need before being activated, but since he's been out for only about two weeks it's not likely to be a long one. He could rejoin the Twins' rotation next week in Milwaukee or back at home versus the Rangers.
