Wrexham boss Parkinson has said of Mullin having to manage a muscle complaint that will require medical attention: “He has also been playing with a problem with his hamstring. He is going to have an injection this week in his back. But he never moans about it, he carries on and never misses training with it, but it is something we have had to wait for this free week to get resolved. What Mulls has done here in terms of his goal ratio is extraordinary; there is going to be a period where it doesn't go his way and we have been able to rest him a few games to keep him fresh, [against Accrington] he was on a different level at times.”
