Dragons back row Nic Cudd is set to make his debut for the Men of Gwent against his former teammates as they travel west this weekend.
Back row Dan Lydiate has undergone successful surgery to his ankle following the injury sustained in last Friday’s game against Edinburgh. He is due to be released from hospital later this week and will return home to recuperate.
The loss of Lydiate has been compounded by the news that fellow back row Hywel Stoddart is expected to miss the rest of the season after suffering a catastrophic knee injury whilst playing for Newport RFC in the Principality Premiership on Saturday.
Elsewhere, lock Rob Sidoli is expected to be unavailable for several more weeks as he recovers from a calf injury.
