The already cloudy picture regarding Padres starting pitching turned darker Wednesday afternoon when it Padres manager Bud Black confirmed that right-hander Casey Kelly has had tests on his right elbow and could be a candidate for elbow reconstruction surgery.

“Anything is possible,” the Padres manager said of the possibility that Kelly would be the fourth Padres pitcher to have “Tommy John” surgery in the last 10 months.

“It is that part of the elbow that we’re concerned about,” Black continued. “The doctors are concerned about what the tests looked like. There’s going to be a lot of discussion between Kelly and his family. They’ll probably want a second opinion.”

Kelly had his elbow examined in San Diego on Tuesday. He returned to the Padres training camp Wednesday morning.

When asked about the possibility of Kelly having “Tommy John” surgery, General Manager Josh Byrnes said: “I’m not sure. We’ll know more soon. I can’t speculate. Hopefully, we’ll get lucky.”
