Toronto, Canada – NEW YORK (Reuters) - Minnesota Vikings back-up linebacker and special teams player Erin Henderson has been suspended for four games for violating league policy on performance-enhancing substances, the NFL said Tuesday.
The suspension is effective immediately and covers the final three regular-season games and the first playoff game for the postseason-bound Vikings (11-2).
The NFL does not specify substances that players test positive for.
Henderson, playing in his second game of the season last Sunday, made two tackles on kickoff returns against Cincinnati and recovered a fumble by a team mate on a punt return.
He is the younger brother of Vikings linebacker E.J. Henderson, who is out indefinitely after breaking his left leg last week.
Minnesota promoted linebacker J Leman from the practice squad to the 53-man roster.
