NEW YORK -- Former New York Jets linebacker Ikemefuna Enemkpali could face discipline from the NFL under its personal conduct policy after breaking quarterback Geno Smith's jaw with a punch in the team's locker room.

Enemkpali and Smith got into a dispute Tuesday before the team's morning walkthrough, and the linebacker slugged the quarterback. Smith likely needs surgery and is sidelined for 6-10 weeks, according to coach Todd Bowles. Enemkpali was released by the team shortly after the incident.

An NFL spokesman said Wednesday that the league is reviewing the situation. Any incident involving workplace violence that occurs off the football field falls under the NFL's personal conduct policy.

ESPN first reported that the NFL is looking into the dispute.

Enemkpali could also face legal charges if Smith pursues them.
