The Czech Republic star has been handed a provisional suspension by UEFA while they investigate claims he racially abused Rangers star Glen Kamara in the last round.
Kudela was seen covering his mouth as he said something to Kamara, before the Rangers man seemed visibly distressed.
Kamara has since accused Kudela of calling him a “f*****g monkey” – something the Slavia man denies.
However, before UEFA’s ban was even announced, Slavia revealed the 34-year-old would miss the trip to north London with ‘health issues’.
This claim was met with suspicion from fans, who refused to believe that was the reason for his absence.
Slavia tweeted at the weekend: “Ondřej Kúdela is not available today due to nasal contusion from the international match between Czechia and Wales accompanied by high fever with antibiotics. Recovery time cannot be determined now.”
Kudela was due to questioned by UK police while in London for the Europa League clash.
Kamara could also be in trouble with UEFA after allegedly acting violently in the tunnel after the incident.
“If I could go back to the time of the game I would walk off the pitch, 100 per cent,” Kamara told ITV this week.
“This kind of thing shouldn’t be in the game. It’s an every day life thing, I don’t know if in our lifetime we’ll ever see it change.
“But I can make a change in some way, I’ll do it. The manager was actually trying to get me off the pitch.
“But I was on my own on the pitch, I couldn’t hear anybody, I was just… different emotions so I wasn’t listening. I had a lot of emotions going through my mind.
“Angry, upset, I felt humiliated. All my family, friends, fans, whoever’s watching. I was taken back a lot. I felt like a little boy. It was a very weird feeling.
“There needs to be a big punishment.
“There has to be a balance. In terms of him getting a one-game ban, I don’t understand.”
