Peyton Manning has been cleared in an investigation into alleged steroid use.

FOXs Chris Hoenig reports:

The NFL says Peyton Manning and his wife, Ashley, fully cooperated with their seven-month investigation, launched after an Al-Jazeera America story suggested they received deliveries of human growth hormone in 2011, while Manning recovered from neck fusion surgery.

The pharmacy intern at the center of the story later walked back his claims.

Several other players named in the report, including Clay Matthews and Julius Peppers of the Packers, James Harrison of the Steelers, and free agent Mike Neal are going to be interviewed by the league in the coming weeks.
