Weber (biceps) was transferred to the 60-day disabled list Friday.
Weber doesn't seem to have made any progress in his rehab program since landing on the disabled list in mid-May, so the Mariners will boot him from the 40-man roster for the time being to allow Tyler Smith and Tyler Cloyd to join the big-league roster. No timetable for Weber's return has come forth yet, but he's now ineligible to return from the disabled list until July 14.
