Wales centre Scott Williams is training with Dragons and head coach Dai Flanagan says it could lead to the offer of a deal.
Williams, 34, left Scarlets last summer and has been looking for a new club.
Dragons are aiming to replace Steff Hughes who is leaving Dragons at the end of October to move to the United States of America to play Major League Rugby (MLR) with Old Glory DC.
Dragons’ current four centre options are Joe Westwood, Aneurin Owen, Harry Wilson and Harri Ackerman, who is recovering from a long-term injury.
When asked whether there was a chance of a contract for Williams, Flanagan replied: “For sure, he is chomping at the bit. He has an itch to scratch and people in that situation are usually determined.
“We only have four midfielders when Steff leaves and I have found out in the past that it can get very thin, very quickly.
“If you lose one then you can lose two or three, so there could be an opportunity to see him [Williams] in a Dragons shirt one day.”
