Williams signed with the Redskins on Tuesday.
Williams move came after the Redskins waived guard Arie Kouandjio (quadriceps), who will miss the entire 2018 season. The 25-year-old will battle for a reserve role on the 53-man roster.
Williams was waived by the Colts on Saturday.
Williams was promoted to the active roster prior to Week 6, but failed to participate in any games. Assuming he clears waivers, the 24-year-old will either look for a new opportunity or land on the team's practice squad.
Williams signed a contract with the Colts on Saturday.
Williams was a member of the Redskins' practice squad prior to the promotion. The 24-year-old will likely serve as a depth option on the offensive line, and replaces the IR-bound Jack Mewhort (knee) on the 53-man roster.
