GREEN BAY, Wis. -- Green Bay Packers president Mark Murphy confirmed Thursday that the NFL will interview Clay Matthews and Julius Peppers, who were named in an Al-Jazeera America report linking them to performance-enhancing drugs.

It was the first acknowledgment by anyone from the Packers' organization of the interviews, which are expected to take place in Green Bay when training camp opens next week.

"The league is pursuing that," Murphy said following the team's annual shareholders meeting. "I know there's been some resistance from the NFLPA about the credibility of some of the sources there, but I don't think we know much more than that."

When asked about the team's involvement in the process, Murphy said: "It's very minimal. It's just setting up the interviews or working with the league office."

Matthews and Peppers -- along with former Packers player Mike Neal -- have denied the assertions of the Al-Jazeera report.

The initial report came out last December and linked several NFL players, including Peyton Manning and James Harrison, to HGH and other drugs.

"I think it's bulls---, to be completely honest with you," Matthews said on Dec. 27. "It's 100 percent falsified, fabricated information. I don't who this guy is. I couldn't tell you what he looks like. I've never talked with him. I've never communicated with him. So for him to bring my name up like that, which appears to be out of thin air, it's bulls---, for a lack of a better term.

"I work hard on my reputation, and really that's all I have," Matthews added. "For seven years, I've worked my ass off. For this guy to say those type of things, it's just not true, and especially for him to recant everything that he said, too, I think it really just goes to show the [type of] source he is, as well. The truth will come out, and I'm not worried about it, because I carry myself a certain way, and that is the right way."

Neither Matthews nor Peppers has been available for comment since the news broke that they would be interviewed by the league at the start of training camp.

Charlie Sly -- the source for the Al-Jazeera report that implicated the NFL players -- has since recanted his remarks. Harrison said earlier this month in an affidavit provided to the NFL that he has never violated the league's policy on performance-enhancing drugs and has never met Sly.
