Texas Rangers pitcher Yu Darvish confirmed that he will undergo Tommy John surgery to repair a torn ligament in his right elbow and will miss the entire 2015 MLB season.

Rangers team physician Dr. Keith Mester and New York Mets medical director David Altchek examined the injured elbow, which revealed the damage. It was then confirmed by world renowned orthopedist Dr. James Andrews, who will be the one to perform the ligament replacement surgery on Tuesday.

Darvish was sidelined by elbow inflammation since August. The Japanese pitcher said that he thought it was just a simple inflammation after testing out fine earlier in the offseason,

Darvish experienced tightness in his triceps before his spring training debut, and several tests confirmed the severity of the injury. The 28-year-old admitted his frustration, but remains optimistic that he will regain his old form.

"Obviously it's a bump in a road for my career and obviously for the team that I'm not going to be able to throw," Darvish said via ESPN. "But there's a lot of positives that can come out of this."

Rangers general manager Jon Daniels also reiterated that the club will not give up on Darvish, while also praising the right-hander's decision to stay in Texas while recovering from injury instead of going back to Japan.

"What was most important to us is that he would rehab in Texas and with the team, both from the standpoint of being with our people, so we could have our hands on him, but also from the standpoint of being with the club, around his teammates, around our staff," Daniels said. "Yu was totally on board with that."

Darvish, who signed a six-year deal worth $56 million with the Rangers in 2012, went 10-7 in 22 starts last season with a 3.06 ERA and 182 strikeouts. He missed the first part of the season as he was put on disabled list due to neck stiffness he suffered in spring training.
