JUPITER, Fla. -- Marlins reliever Carter Capps, who missed a majority of the second half last season due to a right elbow strain, underwent an MRI on Monday after experiencing discomfort in his throwing arm.
Manager Don Mattingly said Capps developed a sore elbow before his last scheduled bullpen session and hasn't thrown since. Due to his injury history, there is concern, because the 25-year-old has missed time the past two seasons due to elbow-related issues.
"Obviously it's concerning any time you've got to stop a guy from throwing," Mattingly said. "But at this point, it's not really to talk about until we get down to exactly what's going on, and where we go from here."

Capps met on Tuesday with the club's physicians. Dr. Lee Kaplan was at Roger Dean Stadium with the Marlins playing the University of Miami in an exhibition game.
Mattingly also added that the results of the medical tests were being sent out for a second opinion.
Capps is one of the hardest throwers in the game. The right-hander was dominant in 2015, striking out 58 in 31 innings.
In Spring Training, the Marlins were planning on opening up the closer competition between Capps and A.J. Ramos.
According to Statcast™, Capps' average fastball velocity was 98.1 mph last year.
The Marlins have late-inning candidates to fill in for Capps, but none are quite the same weapon. Bryan Morris is a candidate to pitch the eighth inning if Capps is out for an extended period. Miami also could pursue trade options.
