Lucas, 31, has played parts of six NBA seasons, most recently making 42 appearances for the Utah Jazz last season. He averaged 3.8 points and 1.0 assist while shooting 32 percent from the field.
The Wizards backcourt has been hit hard by injuries during training camp. Starting shooting guard Bradley Beal fractured his left wrist and will miss the start of the season after undergoing surgery. Glen Rice Jr. is expected to miss the rest of the preseason with an ankle injury.
The Wizards open the regular season on Oct. 29 against the Miami Heat.
