The playing surface failed a morning pitch inspection due to the frozen conditions, leaving latest signings Jon Parkin, David Mirfin and Robbie Gibbons among those left kicking their heels.
"It was a pretty easy decision for the referee in fairness, but we could have done with a game just to give the players we have brought in a match," Knill told the club's official website.
"I think it was equally as frustrating for them. Jon [Parkin] hasn't played football in a while and couldn't wait to play.
"We also had Christian Ribeiro back [from concussion] and he wanted to play, having had an up-and-down start to his time here.
"But it's one of those things, we can't control the weather."
