Schumacher who signed for a nominal fee during the summer will be hoping to see the rest of the season out injury free.
Schumacher has a slight chance of playing some part in the Leeds game next Monday but a more realistic chance would be the trip to Brunton Park and Carlisle United.
The former Everton player has only made 11 appearances which has seen him net just the once with at memorable goal at Swindon Town in a 1-1 draw at the County Ground.
First Team Coach Steve Holland told the official site "Steven Schumacher has successfully returned to training and we are glad to have him back in the pool of players. It is good news for us but the Leeds game next week could be a little early for him."
