Curt Schilling's claim in 2008 that a member of the team's medical staff raised the possibility of treating his injured shoulder with a performance-enhancing drug was "completely baseless," investigations conducted by both the Boston Red Sox and Major League Baseball concluded, according to two baseball sources with direct knowledge of the investigations.

Schilling, now an ESPN commentator, disputed the report.

"It happened. I informed the club, and there were other players that heard the conversation, who I spoke with after," Schilling told ESPNBoston.com in an email. "The club immediately informed MLB, and they launched an investigation in which all parties were interviewed. If someone's saying it didn't happen, I am not sure why, since the two people in the discussion are gone -- I'm retired and the other person was fired last year, I think. But it doesn't shock me that people would deny it was 'an event,' though I am unsure why."

Schilling had contended Wednesday in an interview with ESPN Radio's Colin Cowherd: "It was brought to my attention that [using a banned substance] is a potential path I might want to pursue."

The conversation with the staff member, which according to a source took place during spring training of 2008, was overheard by several teammates, Schilling said. In subsequent interviews, Schilling said it was a member of the medical staff who made the suggestion.

"It was an incredibly uncomfortable conversation," he said, "because it came up in the midst of a group of people. The other people weren't in the conversation, but they could clearly hear the conversation. And it was suggested to me that at my age and in my situation, why not? What did I have to lose? Because if I wasn't going to get healthy, it didn't matter. And if I did get healthy, great. It caught me off guard, to say the least."
