Florida Marlins ace Josh Johnson has been placed on the 15-day disabled list with right shoulder inflammation.
Right-hander Jay Buente was selected from triple-A New Orleans and will start Sunday for Johnson against Tampa Bay.
Johnson's injury had not been previously disclosed.
He went only five innings in his most recent start Monday against the New York Mets, when he allowed one run and was pulled after throwing 85 pitches.
He is 3-1 with a 1.64 ERA in nine starts this year.
The Marlins also transferred infielder Donnie Murphy to the 60-day disabled list on Saturday with a bruised left knee.
