After tearing the ulnar collateral ligament in his right elbow Rockies closer Rafael Betancourt will undergo Tommy John surgery according to the Venezuelan newspaper Mi Diairo.

The team has not yet confirmed the news.

Betancourt 38 said after a Tuesday night loss he did not plan to pursue surgery and instead planned to rehab the arm through platelet-rich-plasma treatment. But he told the Deportes Union Radio network Thursday he changed his mind after consulting with doctors.

"I took the decision last night alongside doctors" Betancourt said on the radio show Los Cronistas. "They told me there was little chance of recovery with current treatment."

Because he did not initially plan to have the surgery many expected that Betancourt had pitched his last Major League game. He was in his fifth year with the Rockies his 11th in the big leagues when he tore the ligament in an Aug. 22 loss to the Phillies.

But the surgery is a strong indication he plans to return to a big league mound.

"It would be sad to come to the end of my career this way after all I've been through" he said. "This motivates me to go on."

Betancourt will see noted Dr. James Andrews on Wednesday and plans to have the surgery in September he said in the interview.
