Philadelphia Eagles offensive lineman Lane Johnson recently filed unfair labor charges against the NFL and the NFL Players Association after he lost an appeal of his 10-game suspension. Green Bay Packers defensive lineman Mike Pennel reportedly took similar action Tuesday.
According to Albert Breer of TheMMQB, Pennel sued the league, NFLPA and NFL Management Council in federal court.
Breer noted the case is related to Pennel's discipline under the substances of abuse policy. The lineman wants a new arbitrator because of a conflict of interest involving the current one, James Carter, per Breer.
