At least five Real Madrid players are facing suspension ahead of the first leg of their Champions League quarter-final at Arsenal.
Vinicius Junior, Luka Modric, Antonio Rudiger, Eduardo Camavinga, Endrick and Lucas Vazquez will be banned from the second leg if they pick up a yellow card.
Eder Militao is also a booking away from suspension, but the Brazilian defender is out injured.
Madrid players have been shown more yellow cards than any other club in the competition, copping 33 bookings in just 12 matches.
For Arsenal, the trio of Declan Rice, Gabriel Martinelli and Jurrien Timber are also walking a disciplinary tightrope.
Champions League rules stipulate that players will be suspended for one match after receiving three bookings.
Slates are wiped clean after the quarter-finals, though.
