Curt Schilling admits he has zero relationship with the Boston Red Sox despite winning a pair of World Series titles with the organization.

"There's a lot of reasons why," Schilling told Kirk Minihane of WEEI.

The 49-year-old went 53-29 over a four-year span in Boston, posting a 6-1 record across eight postseason appearances including an ALCS win against the New York Yankees that featured his infamous bloody sock.

While the marriage between the two sides began well, things turned ugly in the spring of 2008. Schilling agreed to a one-year, $8.5-million deal with the Red Sox prior to that season, but says he suffered a bicep tendon injury before spring training.

Schilling said the Red Sox initially refused to allow him to undergo surgery, and believed he lied to them about the injury when he signed the contract. He said ownership even tried to get their money back.

"I thought I had a very close relationship with all three (John Henry, Tom Werner, and Larry Lucchino), absolutely," Schilling said regarding his relationship with ownership prior to the injury. "That meeting we had when we got together with the player rep, they said things in that meeting that made me realize that they never gave a shit about me.

He added: "The thought that they might think I was lying bowled me over, because I was taking pain meds all through this time. From '04 to when I retired, whenever I needed it. I knew why, because I wanted to pitch, and they wanted me to pitch. But when I was done, they were done.

"I think eventually what it was, was I don't think they really cared anymore about me because they knew I was almost done."

Schilling would never pitch again and officially retired in March of 2009. He was inducted into the Red Sox Hall of Fame in 2012.
