The Dragons have provided updates on injured duo James Graham and Tim Lafai via the club website.
Graham and Lafai went down in the first half of the club's 22-9 loss to Cronulla on Sunday.
Scans on Monday revealed that Graham has suffered a fractured fibula and is expected to miss approximately eight weeks.
Meanwhile, Lafai suffered a syndesmosis injury, but no time frame has been put on when he is expected to return.
The Dragons will provide more information on the centre's availability in "due course."
