Right-hander Shelby Miller, who the Braves traded to acquire Dansby Swanson and Ender Inciarte, has a partial tear of his ulnar collateral ligament and may need Tommy John elbow surgery.
Miller, who pitches for the Arizona Diamondbacks, is weighing surgery or attempting to rehab the injury through non-surgical options.
"It's not good news,” Miller said. “You never want to be put in this kind of situation and never would you think that it would happen to you. It is what it is. It's just one of those things that you can't really control. I'm pretty torn up about not being able to pitch for a while."
The 26-year-old Miller is 2-2 with a 4.09 ERA in four starts this season. He was transferred to the 60-day disabled list on Thursday.
Miller went 3-12 with a 6.15 ERA for Arizona in 2016 while the players Arizona gave up for him had strong seasons.
Center fielder Inciarte hit .291 and won a Gold Glove and shortstop Swanson hit .302 after a late season call-up to Atlanta. Both are struggling this season however. Inciarte is hitting .207 and Swanson has a .143 average.
