The Incident and Suspension
According to the NFL, Jackson violated Rule 12, Section 3, Article 1, which applies to "any act which is contrary to the generally understood principles of sportsmanship." The league stated in a release that "After the game, as players were shaking hands and exchanging jerseys, Jackson struck Buffalo linebacker Bradley Chubb in the face after a brief confrontation."
Reports from NBC Sports and the Associated Press indicate that Jackson was exchanging jerseys with Bills defensive lineman Deone Walker when Chubb appeared to say something to him. Jackson then punched Chubb, knocking his hat off, before Rams tight end Colby Parkinson pulled him away. Chubb described the situation after the game as "just emotions."
Jackson is set to miss the Rams' upcoming games against the Arizona Cardinals and the Las Vegas Raiders. He has the right to appeal the decision. If he appeals, the case will be heard by one of four designated former players or coaches: Derrick Brooks, Jordy Nelson, Ron Rivera, or James Thrash.
