Cheltenham Town's Jordan Wynter has been ruled out for the remaining four matches of the season.
The former Arsenal and Bristol City midfielder picked up a posterior cruciate ligament injury during Saturday's 2-1 defeat at Wycombe Wanderers.
It will keep him out of action for around three months, so Robins senior sports therapist Ian Weston is confident he will be ready to start pre-season training at the start of July.
"Jordan will miss the rest of the season and he'll be in a brace for six weeks," Weston said.
"It's a non surgical injury and it could have been a lot worse for him.
"It's an unusual injury for a footballer, caused by impact, but he's had a consultation, an X-ray and a scan today (Monday) and the brace has been fitted, so he's already on the road to recovery."
Meanwhile, forward Wes Burns has returned to parent club Bristol City for treatment after sustaining an ankle ligament sprain, also during Saturday's match.
Burns is due to return to train with Cheltenham at the end of next week, ruling him out of the games against Cambridge United at home (Tuesday) and Northampton Town away (Saturday).
On-loan midfielder Kane Ferdinand will be fit to return to training later this week, having recovered from a double cheekbone fracture suffered in training.
Central defender Will Packwood (hamstring) has an outside chance of being fit to face Shrewsbury Town on April 25, but he is more likely to return for the final day trip to AFC Wimbledon.
Finally, Asa Hall's recovery remains on course after Achilles surgery, but he will not be considered until next season.
