The league announced Thursday that Guion has been suspended three games for violating the NFL Policy and Program for Substances of Abuse. Guion's appeal was denied, according to NFL Media Insider Ian Rapoport. The 28-year-old was arrested in February on felony marijuana possession charges.
Thursday's development wasn't a shocking one. Guion was aware of the pending suspension for weeks and mounted an appeal.
Now that word is official, the Packers must plan around his loss. Guion broke from obscurity during a strong 2014 campaign that included 3.5 sacks.
