GREEN BAY, Wis. -- Letroy Guion isn't in the clear just yet, at least not with the NFL.

Despite the resolution of his criminal case on Tuesday, the free-agent defensive end could still face discipline from NFL commissioner Roger Goodell whether he returns to the Green Bay Packers or signs with another team.

"It will be reviewed for potential discipline," NFL spokesman Greg Aiello said Tuesday in an email.

Guion could face a fine and/or suspension under the league's personal conduct policy.

The last Packers' player to face a suspension from the league was linebacker Erik Walden. He could not play in the 2012 season opener after he reached a deferred judgment agreement to resolve a disorderly conduct-domestic abuse charge without pleading guilty.

Guion paid a $5,000 fine plus court costs but as a first-time offender, the charges of felony possession of marijuana and a firearm were dismissed without adjudication of guilt.
