Off the back of three successive victories in league and cup, City will make their first ever trip to Rotherham United's brand new New York Stadium this weekend backed by nearly 2,300 supporters.
With opponents Rotherham making no secrets of their own ambitions to gain promotion out of League 2 this campaign, the match is expected to be a good test of City's early season credentials.
Parkinson confirmed that Nahki Wells and Andrew Davies are both pre-match doubts after the pair missed Tuesday's Capital One Cup win at Watford with knocks.
The Bantams boss also admits that his side's performance at Vicarage Road - a team featuring as many as six changes from the previous game against AFC Wimbledon - gave him food for thought ahead of this weekend.
"We'll have to look at both of those two (Nahki Wells and Andrew Davies) in the (Friday) morning - no-one will be risked though," revealed Parkinson.
"We don't want to risk anyone long-term just for one game, especially when we have other good players in the squad who can play.
"Whoever is selected to play though will have to convince myself and Steve (Parkin) that they are fit and raring to go for this one.
"Looking at that (Watford) game, the players who came into that one have given us a difficult decision to make. That is a great thing from our point of view.
"Whenever you go away from home and beat a Championship side, you know that there must have been some good performances in your side to do so."
