Juventus plays Young Boys next in the competition before a double header with Manchester United, with the first match in England on October 23.
The pair had come together with Murillo hitting the deck, and Ronaldo reaching down to make brief contact as he passed by the downed defender.
The Portuguese forward has stolen the headlines tonight for all the wrong reasons after being sent off on his Champions League debut.
Despite playing more than an hour with 10 men at Valencia, Juventus eased to victory. After receiving a straight red, Ronaldo walked away and into the dressing room in tears.
However, there is - of course - an appeals system and the question must be asked: 'was Ronaldo correctly dismissed?'
Ronaldo saw red in a Manchester derby once more, this time for two bookable offences after a trip on Shaun Wright-Phillips and then an inexplicable handball.
Just a month later Ronaldo doubled his count of red cards at the Bernabeu when he elbowed Malaga midfielder Patrick Mtiliga in the face as he tried to escape the Dane's clutches.
Real Madrid got their title defence off to a strong start by convincingly beating Roma 3-0 at home.
The game was stopped around the half-hour mark for an off-the-ball incident concerning Ronaldo and the referee swiftly consulted with one of his fellow officials.
Shorty after the break, Juventus were a awarded a second penalty whhen Leonard Bonucci was brought down in the box.
