Gareth Bale is a doubt for Real Madrid’s Champions League clash with CSKA Moscow after he was taken off injured in the 0-0 draw with Atletico Madrid.
The Welshman was replaced by Daniel Ceballos at half-time after appearing to struggle with a muscle injury in his leg.
Real Madrid felt his absence on the pitch and struggled to create chances against Diego Simeone’s resolute side.
It means Los Blancos have now gone 229 minutes without scoring a goal and missed the chance to go top of La Liga.
Julen Lopetegui’s side dropped points for the second match in succession following the 3-0 defeat at Sevilla in midweek.
The Real boss would have been hoping for a response but it was barely an improved showing on Saturday night.
And it would have ended in another loss had it not been for Thibaut Courtois’ excellence on several occasions, playing against his former club for the first time since returning to Spain.
Atletico were significantly more dangerous in attack, especially in the first half, with Courtois denying Antoine Griezmann and Diego Costa in one-on-one situations.
Real’s best chance fell to Marco Asensio but Jan Oblak was quickly out to smother the danger.
Earlier in the day, league leaders Barcelona also dropped points for the third match in a row as they were held to a 1-1 draw by Athletic Bilbao at the Nou Camp.
Barca boss Ernesto Valverde seemingly had one eye on Wednesday’s Champions League trip to Tottenham as he started with Lionel Messi on the bench.
However, the brilliant Argentinian came on and set up fellow substitute Munir El Haddadi to rescue a late point for the reigning champions.
