Sulser (lat) was transferred to the 60-day injured list Sunday, Christina De Nicola of MLB.com reports.
Sulser is in the midst of a rehab assignment, but he has already been out more than 60 days, so the Marlins were able to free up a spot on the 40-man roster without delaying his return. He will likely be ready to rejoin the big club at some point before August comes to a close.
