Boro have not played since beating Notts County in the FA Cup fourth round on January 28.
Subsequent games against County and Oldham were called off, meaning Stevenage have not been in League One action since January 24 and leaving Smith still waiting to take charge of his first league match.
“The lads want to be playing, and when you’ve prepared physically and mentally for an opponent only for the game to be called off then it is deflating,” Smith told Boro’s official website. “Given the weather, we’ve had to do a bit of moving around from the facility we train at. But the players remain in good spirits and a confident mood.
“Bridging the gap between the match field and training is an important factor but the players are focused. The group is in a great place and there is no problem with motivating these players, their attitude has been spot on.”
The trip to Notts County has been rescheduled for February 22.
Southampton have announced plans for a two-week tour of China as part of their pre-season preparations for the 2018-19 season.
