The Falcons and Williams agreed to terms on a one-year contract Thursday, Ian Rapoport of NFL Network reports.
Aside from opting out in 2020, Williams has earned work in each of the seven pro campaigns that he's been on a roster. Most recently, he turned 56 touches into 267 yards from scrimmage and three total TDs in 12 games with the Bears last year. He'll join a backfield led by Mike Davis (ribs) -- at least for the time being -- meaning Williams is poised to have some type of role out of Atlanta's backfield this season.
