Philadelphia Eagles offensive lineman Lane Johnson lost an appeal of his 10-game suspension for violating the NFL's performance-enhancing drug policy in October. As a result, he filed unfair labor practice charges against the league and the NFL Players Association with the National Labor Relations Board on Tuesday, per Albert Breer of TheMMQB.com.
According to Breer, Johnson also "filed a complaint against the NFLPA with the Department of Labor under the Labor Management Reporting and Disclosure Act."
