The Green Bay Packers defensive tackle Letroy Guion will miss the first three games of the season due to a league ban.
The 28-year-old violated the NFL Policy and Program for Substances of Abuse in the off-season, and will be ruled out until week four against the San Francisco 49ers.
NFL Media claims that Guion appealed the ban, but his punishment has been upheld.
Guion made a career-high 22 tackles in his debut season with the Packers in 2014.
