The NFL Players Association has “blood on its hands” for its "attacks" on Lane Johnson, attorneys for the Eagles right tackle wrote in a new legal filing reviewed by Sporting News.

The latest 31-page memorandum stems from Johnson's attempt to have his 10-game PED suspension from last season overturned retroactively, which would entitle him to collect lost salary as well as have guarantees reinstated in the five-year, $56 million contract he signed in 2016.

The players union and NFL responded separately to have Johnson's claim dismissed without prejudice. The latest filings from all three parties came Wednesday in the U.S. District Court of Southern New York.

Johnson’s suspension was his second in four NFL seasons with the Eagles. Johnson, though, claimed this positive test stemmed from ingesting an NFLPA-approved supplement that contained a prohibited substance under the league’s drug-testing policy.
