In a nutshell, catcher Joe Mauer is healthy again. However, he feels that he rushed into things during Spring Training and blames that on his bilateral leg weakness and problems both offensively and defensively. It also doesn't help that he lost 15 lbs. due to the undisclosed viral infection that has his rehab a week behind schedule.
Long story short: there is no timetable for Mauer's return. He will be sent to the minors for some rehab games before returning to the 25-man roster. When that will happen is anyone's guess.
