Roger Clemens, on "60 Minutes" Sunday night, says he's been wrongly accused of steroid use by former trainer Brian McNamee.

NEW YORK — Roger Clemens might be willing to take a lie-detector test, was "shocked" close friend Andy Pettitte used human growth hormone and, in his first interview since the Mitchell Report, said — again — that he probably will retire.

Sounding indignant and defiant during the nearly 14-minute segment broadcast on CBS's "60 Minutes" Sunday night, Clemens appeared to set up a confrontation with former personal trainer Brian McNamee in front of Congress, which has asked the pair to testify under oath at a Jan. 16 hearing.

Clemens, a fiery look in his eyes and stubble on his face, said he would have spoken with baseball drug investigator George Mitchell had he been aware McNamee accused him of using steroids and HGH. Clemens said the cost of litigation had made him wary of filing a lawsuit against McNamee, who also has threatened to sue his former boss.

The seven-time Cy Young Award winner, the most prominent player implicated in last month's Mitchell Report, steadfastly maintained his innocence and called McNamee's allegations "totally false."

In excerpts of the Dec. 28 interview that were released Thursday, Clemens said McNamee, his former personal trainer, injected him with vitamin B-12 and the painkiller lidocaine. In the full 14-minute broadcast, Clemens also said he was given an injection of toradol under the supervision of the New York Yankees.

McNamee told Mitchell he injected Clemens with steroids and HGH about 16 to 21 times during 1998, 2000 and 2001 — before baseball players and owners agreed to ban performance-enhancing substances.

"If he's doing that to me, I should have a third ear coming out of my forehead. I should be pulling tractors with my teeth," Clemens said in the interview, taped at his home in Katy, Texas.

He said his lawyer advised him not to speak with Mitchell, who spent 20 months on his investigation.

"If I would've known what this man, what Brian McNamee (had) said in this report, I would have been down there in a heartbeat to take care of it," Clemens said.

Only two active players, Jason Giambi and Frank Thomas, spoke with Mitchell, a Boston Red Sox director.

On Friday, Clemens did speak with McNamee by telephone, an individual close to the situation said. The conversation first was reported Sunday by Newsday.

The individual would not say what was discussed between the two.

Clemens is scheduled to hold a news conference today in Houston, part of his campaign to clear his name. In addition, the House Committee on Oversight and Government Reform has asked Clemens, Pettitte and McNamee to testify, heightening the stakes and putting them potentially in legal jeopardy.

Former Yankees teammate Chuck Knoblauch, McNamee and former Mets clubhouse attendant Kirk Radomski, who allegedly supplied McNamee with performance-enhancing drugs, also have been asked to testify.
