Gareth Bale has questioned the UEFA rules that will leave Wales without key men Aaron Ramsey and Ben Davies for their Euro 2016 semi-final against Portugal in Lyon.
Ramsey took up Bale's customary role of talisman in the quarter-final against Belgium last Friday, turning in a virtuoso performance in the 3-1 win.
But the Arsenal midfielder and Tottenham defender Davies both collected a second booking of the tournament in that memorable triumph, making them unavailable for the most important match in Welsh football history.
"It's horrible," said Bale, lamenting their fate - one also suffered by Portugal midfielder William Carvalho
"The rules are difficult to take, sometimes you wish at this stage of tournament yellow cards would be wiped.
"You feel for them and they'll be hurt, but they're not showing it and they've given us more motivation to win so they can play again.
"We're playing for the nation and the badge but also for them."
The match is being billed as a showdown between Real Madrid superstars Bale and Cristiano Ronaldo but the Welshman believes the potential absence of another Bernabeu man for Portugal could have a significant impact.
Centre-back Pepe missed training on Monday due to a thigh complaint.
"Firstly he's a fantastic player. He's incredible for Real Madrid, professional and a great man who's been very good to me.
"He'll be a big loss if he's not fit but if he does play he'll make it difficult."
While Wales are breaching new ground, Portugal are in the semi-finals for the fifth time in their previous seven attempts at the European Championships, but Valencia midfielder Andre Gomes rejects the notion of them being favourites.
"I never heard of favouritism in the semi-finals," he said. "If they came here is because they have merit.
"There are no favourites. The squads arrive here with all the credit. We will try to give our maximum, as well as them."
Gomes missed out when Portugal - who are still yet to win a game inside 90 minutes at the tournament - overcame Poland on penalties due to a thigh problem but the 22-year-old is confident he can play a part at the Stade de Lyon.
"Physical problems are things we have no control over," he added. "I have tried to improve every day and now I am feeling better.
"I have already returned to training with my team-mates. Now I will try to improve until the next game to give my contribution, on or off the pitch."
Crystal Palace midfielder Jonny Williams is favourite to edge out Leicester City's Andy King as Ramsey's replacement, while Fulham's Jazz Richards could come in for Davies, with Chris Gunter moving inside from right wing-back.
Danilo is expected to get the nod in the holding role for Portugal with Carvalho unavailable.
