Manchester City will have to do without Fernandinho and Nicolas Otamendi in the second leg of their Champions League tie with Schalke.
Both City players were shown yellow cards in Wednesday's last-16 first leg in Gelsenkirchen, and will be out for the second leg on March 12 at the Etihad Stadium.
The pair were each carded for fouls that led to penalties for the home side, with Nabil Bentaleb converting both spot-kicks to give Schalke a 2-1 half-time lead.
Sergio Aguero gave City an early lead with a tap-in following a mistake from Schalke playing out of the back.
