Chesterfield's head of sports science and medicine Rodger Wylde gives an insight into the current injuries in the Spireites squad ahead of the game against Derby County in the FA Cup.
With league and cup games following in quick succession, the Spireites' squad is under extra pressure, and Wylde fed back on those currently in his treatment room.
“The worst injury at the moment is Gary Roberts," said Wylde. "He sustained a hamstring injury at Swindon and we had a MRI scan this week, which confirmed our diagnosis."
"From now we are expecting Gary to be out for about six weeks.”
Goalkeeper Aaron Chapman is recovering well from ankle surgery, and Wylde spoke in more detail about the 24 year-old's condition.
He said: “Aaron has very laxed ankles genetically, his ankles invert and they turn in. He's said his mum is exactly the same so he has obviously inherited it from her.
"Because the left one was letting him down, we had to have his lateral ligament reconstructed about 12 weeks ago, but he is now back in training and in intensive rehab.”
Full back Drew Talbot has made appearances on the bench in recent weeks, but Wylde says the defender is continuing to progress well.
“When I first came here over a year ago," said Wylde. "Drew had problems with his groin, even though he was in the team.
"It’s taken a lot of time and Drew's suffered minor setbacks, but he is now back in full training and looking well."
