Richie Myler will miss the next six weeks after picking up a groin injury.
The former Warrington halfback suffered the blow in last week’s narrow victory over Huddersfield, with scans revealing he had picked up the injury.
If Myler is out for the full six-week period, he will miss crucial games against St Helens, Warrington and Wigan, as well as games against Wakefield, Hull KR and Leeds.
Myler has impressed throughout the year and was recently touted for an England call-up by Dragons head coach Laurent Frayssinous.
