The 32-year-old was sent off after appearing to attempt to throw ice at the referee while furiously protesting a decision that went against his side.
Rudiger had to be physically restrained by his teammates and now Germany legend Lothar Matthaus has urged La Liga to give him a lengthy ban.
Matthaus said on Sky90: "He went crazy, he was no longer in control. He's a German international, he should be a role model. Yesterday he forgot all about that."
He added: "If he walks away with a four-week suspension, he can be satisfied. I'm more thinking of a double-digit ban. I expect a massive ban. Besides, he was on probation."
The centre-back has since apologised for his actions and it is yet to be determined how long a potential ban will be.
