NFL says NFLPA has a duty to cooperate in PED report review

The NFL and the players union continue to bicker over an inflammatory -- and since denied -- Al-Jazeera America report linking several prominent players to PEDs.

The league filed the latest salvo, saying that the NFLPA should cooperate with the investigation in an email to the Pittsburgh Tribune-Review.

The players named in the report, which were based on the claims of a supplement salesman named Charlie Sly, were since-retired Denver Broncos QB Peyton Manning, Pittsburgh Steelers linebacker James Harrison, Green Bay Packers linebackers Julius Peppers and Clay Matthews, and free-agent linebacker Mike Neal.

Harrison responded in his own way on Sunday, saying he'd meet with the league, but only on his terms.

The NFLPA, however, maintains that the league has no basis to seek interviews with the players named in the report at all.

Again, from the Trib-Review:

The league's spokesman says the NFL has responded to the request for additional evidence, but Atallah contends there was "nothing substantive at all," included.
