Lucas, who can also operate at fullback, was last week released by the Reds along with Izack Rodda and Harry Hockings, after they refused to take pay cuts to ease Rugby Australia finances.
The Rugby Paper reports that Lucas, who is one of four rugby playing brothers, will have the pick of five clubs who are interested in signing him.
As well as Warriors, Edinburgh, Munster, London Irish and Bath all have Lucas in their sights.
