It was an off-the-ball incident during which Murillo and Ronaldo collided while running towards Valencia's box, before the Portuguese was believed to pull the Colombian defender's hair seemingly in protest to the way the centre-back went to ground.
Jacobelli also rounded on Brych for having "invented" a last-minute penalty awarded to Valencia - which home captain Dani Parejo then missed - concluding that the 43-year-old "should be expelled from the Uefa ranks for his shameful handling of the match".
Despite Ronaldo's dismissal, Juventus recorded an impressive 2-0 win at the Mestalla Stadium, with Miralem Pjanic scoring twice from the penalty spot.
Ronaldo looked baffled and kept professing his innocence, sitting down on the pitch in disbelief.
It remains to be seen how Uefa judge Ronaldo's offence, and dissent, but he is set to miss the next European game at home to Young Boys on October 2.
Juventus coach Massimiliano Allegri insisted it shouldn't have been a red card, and lamented the fact that video technology has yet to be introduced into the Champions League, as it has been in Serie A. VAR was also used at the World Cup in Russian Federation this year.
Meanwhile, Gareth Bale scored as Real Madrid moved on from the departures of Cristiano Ronaldo and Zinedine Zidane with a 3-0 win over Roma to confidently launch their pursuit of a fourth successive Champions League title.
"It is disappointing because we will lose an important player for at least a match".
"You could say he's increased the players' desire to prove themselves", Allegri said. "He was saying he didn't do anything", Marcelino said.
After drawing three blanks in the Italian top flight the ex-Real Madrid man finally broke his duck last weekend, scoring twice to mastermind a 2-1 win over Sassuolo that keeps the Bianconeri at the Serie A summit with a flawless record so far. A red card in the Champions League results in an automatic one-game ban with no right of appeal.
Ronaldo started brightly, with an ambitious shot from distance, and then had a hand in teeing up two glorious chances.
Cristiano Ronaldo's sister, Katia Aveiro, has come out in defence of him after his red card.
Parejo stepped up but Wojciech Szczesny saved his spot-kick to sum up the Spanish side's frustrating evening.
