The prop was forced off the field early in the second half of the game, and following further investigation, Head Physio Chris Towers says that Jones faces a spell on the sidelines:
"Duncan suffered damage to the medial ligament of his knee" Towers confirmed.
"In terms of prognosis, we are looking at something around an eight week lay-off to allow him to heal and regain his strength and fitness to get back playing again."
