The NFL says that it’s conducting a comprehensive investigation of the allegations by Al Jazeera that Denver Broncos quarterback Peyton Manning had human growth hormone delivered to his house.
The NFL doesn’t have a timetable for finishing the review, but it’s not expected to be completed before Manning leads the Broncos in the Super Bowl against the Carolina Panthers on February 7th.
Manning has strongly denied using performance-enhancing substances.
