Scans have confirmed a season-ending ACL injury to young defender Nick Coffield.
The 22-year-old left the training track on Friday after injuring his right knee during match simulation.
“Nick had been doing everything right this pre-season and we were really looking forward to seeing what he could achieve this year,” Chief Operating Officer Simon Lethlean said.
“This is a big blow to Nick, but we know he’ll be doing everything he can to get back out there as soon as possible.
“While this is a significant setback, Nick has the full support of the entire Club as he attacks his rehabilitation.”
