The midfielder has been out since early September with a problem at the top of his thigh.
But he's stepped up his rehabilitation this week and completed his first ball work in seven weeks at Spurs Lodge on Tuesday.
"I've started running this week, straight running on Monday and some ball work and twisting and turning on Tuesday," said Simon this morning.
"We decided to see if doing a bit of work would help strengthen it and now it's all about how it reacts. So far I've been pain free and I'll be able to continue building it up.
"It's early but so far, so good. It's was just great to be out there again and I can't wait to get back."
Naturally, Wales' two-legged play-off against Russia has been at the back of his mind and the biggest games of his country's recent history are approaching fast - the away leg is in Russia on Saturday week, November 15.
"Of course I'm realistic about it but I'm not ruling myself out yet - it depends how well this week goes," he added. "I'll then speak to the Welsh people and see what they want to do, they might want me to go down there anyway.
"The home game will be the biggest night in Welsh football for a very long time so I'll be there whatever."
Simon Davies has some positive news at last - but remains realistic about his chances of making Wales' Euro 2004 play-off next week.
