Michael Brantley has been sidelined for six weeks and there's no timetable for his return to the Houston Astros.

Brantley is currently away from the club as he seeks a second opinion on his injured right shoulder. Acting manager Joe Espada declined to elaborate when asked whether that meant surgery was on the table.

The 35-year-old is hitting .288/.370/.416 with five home runs and 26 RBI in 277 plate appearances this season.
