Chesterfield are waiting to discover the extent of the hamstring injury Gary Roberts sustained at the weekend.
Roberts limped off in the closing stages of the 3-1 defeat against his former club on Saturday. The winger, 30, has had recurring hamstring trouble this season and he looks set for another spell on the sidelines. Immediately after the loss at the County Ground, Chesterfield boss Paul Cook said the injury "doesn't look a good one, so that's a big blow for us". Roberts will undergo a scan on Monday and Spireites head of sports science and medicine Rodger Wylde told the club's official website: "The issue this time is with his other hamstring. It was his right and now it's his left hamstring. "What happened was that Robbo was sprinting towards the touchline for a ball and then when he reached the ball he decided to back heel it. "The hamstrings are a very complex group of muscles, when you're sprinting half of the muscles is contracting and half is relaxing, and in back heeling the ball he's completely changed the dynamics of the movement and his hamstring couldn't cope with it. "An analogy of that could be travelling in a car at 60 miles per hour and then quickly trying to put the car into reverse, which causes incredible strain on the area. "He's having a scan today [Monday] and we'll see if it's a grade two or a grade three hamstring strain. After the scan we'll know more about how to progress with the injury. "In all likelihood we could be looking at six weeks of recovery work, if it's a grade two injury, but we'll be able to make a better recovery schedule once we've received the scan results."
