Miami placed newly acquired starting pitcher Colin Rea on the 15-day disabled list with right elbow soreness Sunday morning, the club announced.
Rea will undergo an MRI on Monday, according to MLB Network’s Jon Morosi.
Rea had pitched well through the first three innings of his Marlins debut but then signaled to the trainers in Miami’s dugout after striking out Jedd Gyorko with one out in the fourth.
The Marlins initially listed Rea as day-to-day Saturday night. It’s unclear whether he will miss more than two weeks.
Rea was plagued by elbow issues last September, according to Dennis Lin of The San Diego Union-Tribune.
Miami acquired Rea and Andrew Cashner from the Padres on Friday morning, and the organization slotted him into the back-end of the starting rotation.
Over 99.1 innings with the Padres before getting traded, Rea pitched to a 4.98 ERA and 4.75 FIP.
The Marlins recalled Nefi Ogando in the corresponding roster move. Ogando gives the club bullpen depth until it needs another starter.
Miami could consider trading for another starter in Rea’s absence.
