KANSAS CITY -- Royals left-hander Danny Duffy will undergo a procedure in Kansas City on Tuesday to remove "loose bodies" in the back of his elbow, manager Ned Yost said.
Duffy had mentioned almost three weeks ago that there was an issue in the elbow area that was causing pain and inflammation.
"I have what I have," Duffy said then. "It's something that is inflaming something in there. So we'll get it looked at when we need to. But until then, right now, I could go. Nothing in my elbow is going to compromise my ligament."
Duffy also said he felt a little bit of inflammation last offseason, but thought he could pitch through the discomfort this season.
"I have a high pain threshold," Duffy said.
Duffy didn't start feeling any noticeable pain until August. He eventually was diagnosed with a low-grade pronator strain and was placed on the disabled list.
"A lot of players have slight tears or chips or whatever and play through it," Yost said. "You don't address it until you have to, until it affects your performance."
Duffy said he should be fine for Spring Training after the procedure.
