Williams, 31, sat out all of last season because of issues with the Redskins' medical staff and former team president Bruce Allen. The veteran offensive tackle revealed last October that he had a cancerous growth, a rare form of soft-tissue cancer known as dermatofibrosarcoma protuberans, removed from his head that went undiagnosed for about six years.
Williams said the misdiagnosis played a large part in his lengthy holdout last season and his distrust of the Redskins organization, eventually leading to his demand for a new contract or to be traded.
The former No. 4 overall pick would have reported to the team last year if the Redskins guaranteed the final two years of his contract, according to ESPN. Williams now has one year and $12.5 million remaining on his deal, with none of the money guaranteed.
Before sitting out in 2019, Williams was named to seven consecutive Pro Bowls (2012-18). He was a second-team All-Pro choice in 2015.
