Manning clears cloud of HGH allegations

The NFL says it found no credible evidence that Peyton Manning was provided with human growth hormone or other prohibited substances as alleged in a documentary by Al-Jazeera America last year.

The league said on Monday the quarterback and his wife Ashley fully cooperated in the seven-month investigation, providing interviews and access to all records sought by investigators.

The NFL is continuing its investigation into allegations made against other NFL players in the documentary, which the league said involves "different lines of inquiry and witnesses."
