Richardson was arrested for speeding and resisting arrest last July. He originally pled not guilty to the charges in August of 2015, but later amended the plea to guilty.
The talented defensive lineman was suspended the first four games of 2015 as a result of a violation of the NFL's substance-abuse policy.
The full statement from the NFL:
Sheldon Richardson of the New York Jets has been suspended without pay for the first game of the 2016 regular season for violating the NFL Personal Conduct Policy.
Richardson will be eligible to return to the Jets' active roster on Monday, September 12 following the team's September 11 game against the Cincinnati Bengals.
Richardson is eligible to participate in all preseason practices and games.
The Jets suddenly are getting thin at their biggest area of strength. Damon Harrison left in the offseason to sign with the Giants. Muhammad Wilkerson is in a stalemate with the team over contract talks and hasn't signed his franchise tender. Leonard Williams is talented but coming into just his second year.
Richardson coming back the second week will certainly help, but a defensive line long perceived as a strength has some issues to start the season.
