Christian is in contention to make his debut.
The player came through 78 minutes of a behind-closed-doors game against Rangers on Monday without any reaction.
He is fit enough to be considered for the matchday squad by Thomas Frank.
After returning to action for the first time since suffering a cardiac arrest on the pitch in June last year, the Denmark international has impressed.
After leaving Inter Milan by mutual consent, Eriksen moved to a free agent deal with Brentford.
The rules in Italy would not allow him to play after having an ICD device fitted.

Frank feels that former Spurs player Christian Eriksen is ready to make his competitive debut after spending time building up his fitness with his former club.
Christian will be in the squad. He will play his first game tomorrow. Frank said it would be a big day for all of us, but especially Christian and his family. He walks out on the pitch.
Everyone saw what happened on the pitch at Euro 2020 and it reminded us that we are privileged to do what we do.
The key thing is that everything has been checked and it is all good. He and his family are in agreement that he should play football.
Frank knows what he can bring to his side, who are in danger of being dragged into the scrap.
Frank said that he is the player with the biggest CV who has ever played for the club. He has been doing amazing things when he is training.

There are small conversations with players about where to put the ball when you give it to others, when they should be cool on the pitch.
He is very confident in what he can do as a footballer, but also very humble.
Frank said that Christian is in a good place. He needs to get that game rhythm into his body and get consistency in everything.
We will need a few games to get him going under max, but I would not put him in there if I did not think he could provide something now.
Since the turn of the year, the Bees have lost six games in a row and are now only four points above the drop zone.

You always try to look up the table, but I am not stupid. Frank said that he knows other teams are winning, but the only thing they can focus on is themselves.
The way we have been approaching the league has been the same as it was in the Championship, just one game at a time.
It will be the same for this game - our approach needs to be front-footed, brave, aggressive and cool. If we put in performances like that, it will turn around with wins and draws.
If we go into this game with a different approach, that will be an incident. It will be the smallest of margins which decides the game tomorrow.
