Ronaldo was the inspiration behind that Spanish record-winning streak but he had one of his poorest matches in a Real shirt in the 2-1 victory over Cordoba on Saturday, the win coming through a late penalty from Gareth Bale.
Real still lead the La Liga table by a point and have a game in hand but they have an in-form Barcelona breathing down their necks.
While Real are stuttering, Barca have clicked into gear and tore apart Elche 6-0 and Atletico Madrid are also looking strong, four points behind after a 3-1 win over Rayo Vallecano.
Ronaldo was unable to make an impact against Cordoba and his frustration saw him lash out with his hand against Jose Crespo which the referee missed and then minutes later he was sent off for kicking out at Edimar.
He was quick to apologise on Twitter after the game but he is now likely to be suspended for the next two matches against Real Sociedad and Sevilla but could also miss the derby with Atletico.
It was generally a disjointed match from Real whose rhythm and link-up play has dropped noticeably in recent weeks.
