Buffalo Bills running back Karlos Williams returned to practice on Monday after missing the team's previous three games due to a concussion.
Williams suffered the injury against the New York Giants in Week 4, but after the Bills' bye in Week 8, the running back has been cleared to return to the field.
It's still unclear if Williams will be ready to play on Sunday against the Miami Dolphins, but his return to practice this early in the week in an encouraging sign.
Williams has 42 carries for 226 yards and three touchdowns this season.
