Padres right-handed pitcher Andrew Cashner will likely miss the start of next season after having surgery to repair a knife puncture wound to the thumb on his pitching hand.

According to Padres general manager Josh Byrnes, Cashner was on a hunting trip and was accidentally stabbed by a friend while the pair was trimming a carcass.

Although it took only two stitches to close the wound, the blade lacerated a tendon in Cashner's thumb forcing the surgical repair.

"It's a three-month recovery," said Byrnes. "The doctors don't expect any long-term consequences. He'll be behind. To say he'll be ready by Opening Day is unrealistic."

Cashner, who was expected to compete for a spot in the Padres starting rotation, will most likely join Cory Luebke and Joe Wieland on the disabled list for Opening Day. Luebke and Wieland are recuperating from "Tommy John" elbow reconstruction surgery.
