Dragons back row Nic Cudd will miss the rest of the season after suffering a knee injury at a practice session.
The 30-year-old will undergo operation and ruptured an anterior cruciate ligament in his knee.
He joins a set of players including wing Ashton Hewitt and prop Aaron Jarvis who are very likely to sit out the rest of the season that is Pro14.
It means interim coach Ceri Jones is without almost 20% of the squad for the match with Benetton.
But there’s good news on Ryan Bevington (concussion) and Brandon Nansen (hamstring), with both expected to return to activity in March.
