The NFL Players Association continues to resist the NFL's attempt to interview the active players named in a six-month-old Al-Jazeera America report on performance-enhancing drugs, but retired quarterback Peyton Manning is likely to cooperate if requested.
The players' union sent four letters Tuesday -- one on behalf of each player -- in response to the NFL's letter last week asking to interview those named in the report. Those players are Pittsburgh Steelers linebacker James Harrison, Green Bay Packers linebackers Clay Matthews and Julius Peppers and free agent linebacker Mike Neal.
