Aaron Pressley has suffered a hamstring injury that's expected to keep him out for a number of weeks.
Our physio Tim Maynard said that he's awaiting the results of a scan on Thursday to assess the extent of the damage.
Robbo said: "It's really disappointing to lose Aaron for a spell due to injury. He's been a big part of what we are trying to achieve and he will continue to be once he's back fit. We will be looking after his rehabilitation and getting him back to fitness as soon as possible.
"With January around the corner we are looking at other options available to us."
