Joe Mauer (concussion) has shown improvement in recent days, but will not travel with the team for their weekend series against Texas. Mauer was told earlier in the week to take it easy for a few days, and it seems to have done him some good. There is still no timetable for when he'll resume baseball activities, though it's extremely likely he returns at some point this season. Ryan Doumit and Chris Herrmann will continue to handle the catching duties in his absence.
