Yu Darvish was relieved to receive the elbow diagnosis he did earlier this week as he was questioning what was wrong with him.

The Chicago Cubs shut Darvish down for the season with a stress reaction (bone bruise) in his right elbow.

"Until the diagnosis, there was some time I thought it could be my mental side because there was an unknown factor," Darvish said through his interpreter. "With the diagnosis, I'm relieved to know what that something was."

The injury had been left undiagnosed from late May until a few days ago and the right-hander was aware of the criticism he was receiving.

"A person can't really tell how much an injury hurts because you're not that person," Darvish said. "It's natural for me to receive those kinds of comments towards me because they don't really understand where the pain is and how much the pain is."
