Allen has been sidelined with a hamstring injury he picked up in the Capital One Cup victory over Notts County in August.
The Wales international is now close to returning to fitness and hopes to be available for the trip to St James' Park, admitting he sees it as a fresh start for him after picking up the injury so early into the new season.
"I'm almost there, basically," Allen told the club's official website. "The plan is to get back into training, get a good few days leading up to the Newcastle game and hopefully I'll be available for selection from there on.
"It has been a bit of a frustrating time - it always is when you're injured - but I'm finally getting there. It was the one I had in the back of my mind anyway, so it has worked out quite nicely in that sense.
"I was disappointed; I thought I would get back for the Wales games but unfortunately they just came a bit soon. But it has meant that I got a bit of extra rehab leading up to that game. I have been able to get ready.
"With the timing of the injury, I hadn't really got into the swing of things. This is a fresh start of the season for me personally. It is great to come back with the team doing so well."
