Only three days after their win at Leyton Orient, Parkinson's men will look to go again and try to make it four wins on the trot in all competitions with victory over the Saddlers.
City will have to take on Walsall without the influential trio James Hanson, Andrew Davies and Filipe Morais, however, after all three players picked up injuries at Orient.
With Jon Stead still struggling with an ankle wound and James Meredith a slight doubt due to a foot problem as well, Parkinson knows City will be depleted for the Walsall match.
Whoever is selected for Saturday though, Parkinson is sure they'll be ready and raring to go.
Parkinson said: "We have injuries in the squad, we know that, but on the reverse side of that, we've seen Gary MacKenzie and Francois Zoko given an opportunity to play on Wednesday.
"That is good for the morale of the squad. As the likes of Billy Clarke and Mark Yeates have shown in recent games, the challenge is there to get into the side and stay in it, especially if you've had a spell out.
"We always knew that every player would figure during this busy run of games we have in February and March.
"We obviously didn't expect to get three or four injuries in one night but we will have to deal with that.
"We will be prepared for Walsall the best we can and we'll give it our best shot.
"We spoke to the lads about being mentally tough and being ready to go again
"The training we have done for this game has been more about team work and shape. We don't want to take anything from the lads (in terms of energy levels) at all going into this next game.
"We'll be ready for hopefully another good day."
Although Parkinson is confident City will have what it takes to rally and push on in another game, he also knows that the Bantams followers will have a huge role to play during the game.
Parkinson added: "Given the injuries we've got and the fact that we played on Wednesday when Walsall had a free week, we are going to need the crowd more than ever to roar us on this Saturday.
"They are going to play such a key part this game, probably more than any other recent league match we've had.
"I'd like to ask the supporters coming to the ground on Saturday to identify with the week we've had and really get right behind the team.
"Every game is crucial from here until the end of the season and we need them to get the ground rocking come Saturday afternoon. That would give the lads a huge lift."
