The tall defender has only played once since September and went to see a specialist earlier in the week about the problem.
But the advice from the specialist is that rest should cure the wear and tear in the knee and Anthony is hoping to return to full training in a couple of weeks.
Boss Glenn Hoddle confirmed today: "It's good news with Anthony. He won't need an operation. We thought he might need one on the knee problem he's had.
"He's been out now for four weeks now and he's just started to do some running again.
"It's been stop-start for him ever since he's been at the club. He had a terrible injury with his knee ligament 18 months ago and it's been very frustrating for him. I'm sure he'll get there in the end though."
Anthony Gardner has received a boost - he will not require surgery on his troublesome knee.
