Head coach David Wagner is once again expected to rotate his line-up for the Carabao Cup, given the busy travel schedule over the week.
The Canaries made the trip to Huddersfield at the weekend, winning 4-0, before now heading to Bristol before another away trip to Rotherham on Saturday.
Wagner has already lamented the loss of Josh Sargent, who picked up an ankle injury as he opened the scoring at the John Smith's Stadium.
"It looks like a serious ankle injury unfortunately. We will assess him tomorrow, and then we will have to wait and see how serious it actually is," Wagner said.
"We will assess the group, then we will make a decision \[on who plays\] on Tuesday morning. But as we've seen, there are a lot of players pushing for the starting spot. We will see who will start and who will come on."
Kellen Fisher and Jaden Warner, both of whom had been involved in the first-team matchday squads of late, were given minutes with the Under-21s on Friday night as they beat Chelsea 3-2 at Carrow Road.
That pair, along with the substitutes that Wagner says made an impact against Huddersfield, will all be in contention for a starting spot on Tuesday night.
"There are a lot of players pushing for the starting shirt. The substitutions made a big impact again so on Tuesday, we will see who will start and who will come on.
"We made the decision that Kellen and Jaden would not be involved in the matchday squad (v Huddersfield) to give them gametime.
"They will be involved on Tuesday for sure but I wanted to give them the chance to play against Chelsea, a great result for our Academy and a very good performance which was important."
