Zack Greinke will fly to Los Angeles today to have his right elbow examined by team Dr. Neal ElAttrache.

The team said that Greinke experienced “mild irritation” in the back of his elbow while throwing on Sunday and “does not feel 100 percent comfortable” in the elbow. He threw a full bullpen without pain Friday.

Hyun-Jin Ryu, who was scheduled to relieve Greinke against the Milwaukee Brewers, will start instead. The game is scheduled to begin at 1 p.m.

Update: Don Mattingly said that an MRI on Greinke’s elbow came back clean and the pitcher said he could make his scheduled start if he wanted to. “If something serious was going on,” Mattingly said, “it’d be a shocker.”

Update 2 (2:38 p.m.): Dr. ElAttrache confirmed the diagnosis of inflammation in the back of the right elbow. Greinke received an injection of platelet-rich plasma and anti-inflammatory medication. He will rest for 2 to 3 days and then return to a progressive throwing program.
