Real Madrid captain Sergio Ramos has rowed back on his suggestion he deliberately earned a yellow card against Ajax on Wednesday to ensure he would be banned for the second leg.
Madrid will carry a 2-1 advantage back to the Santiago Bernabeu but Ramos will miss the return, after being booked for a rash tackle on Kasper Dolberg, two minutes after Marco Asensio's 87th-minute winner.
Three yellow cards brings a one-match suspension but Ramos may have seen sitting out the second match against Ajax as preferable to a punishment in the quarterfinals.
UEFA could add another match to his ban. Madrid defender Dani Carvajal was suspended for two games last season after intentionally earning a booking in the group stages.
"The truth is that given the result I'd be lying if I said it wasn't something I had in mind," Ramos had said after the game.
Around an hour later, Ramos appeared to backtrack on Twitter. He wrote: "I want to make clear that it hurts me more than anyone, I have not forced the card, as I didn't against Roma in my previous game in the Champions League.
"I will support from the stands as a fan more with the hope of playing in quarters."
