Curt Schilling reported the 2008 incident in which a staff member suggested he take human growth hormone to then-Red Sox general manager Theo Epstein, who contacted Major League Baseball and MLB conducted an investigation.
MLB spokesman Pat Courtney confirmed that an investigation took place, but would not divulge its outcome.
Schilling told Peter Abraham of the Boston Globe that he was "kind of mad" Epstein went to MLB, saying, "I was trying to downplay the whole thing because I wasnt playing at the time and I didnt want to cause any problems in the clubhouse". He added: "Had I known Theo was going to report it to MLB, I would have never said anything."
Schilling -- who earlier had said the individual was not uniformed personnel or a member of the Baseball Ops department -- told Abraham it was not former medical director Thomas Gill or former head athletic trainer Paul Lessard.
