Roger Clemens says he was injected with "Lidocaine and B-12" and not steroids or human growth hormone by former trainer Brian McNamee, according to a portion of an interview with CBS' "60 Minutes" released Thursday. "Lidocaine and B-12. It's for my joints, and B-12 I still take today," Clemens told Mike Wallace in the interview, which is scheduled to be shown Sunday night. It is Clemens' first interview since the release of the Mitchell Report in December. In the report, McNamee claims to have injected Clemens with steroids in 1998, 2000, and 2001. He said he injected the seven-time Cy Young winner with HGH in 2000, according to the report. According to CBS, Clemens calls the accusation that he used steroids and HGH "ridiculous" and says he "never" used any banned substances. The interview was conducted last Friday. Wallace asked Clemens if he swears he didn't used banned substances. "Swear," Clemens responds.
