UEFA has opened disciplinary proceedings against Cristiano Ronaldo following his red card for tugging on the hair of Valencia defender Jeison Murillo.

This is what it means for the Juventus star.

When will we find out how long Ronaldo is banned for?

The case will be dealt with by the UEFA Control, Ethics and Disciplinary Body (UCED) on Thursday, Sept. 27. It will then be announced exactly how many games Ronaldo will be banned for.

How many games will Ronaldo be banned for?

Ronaldo gets an automatic one-game Champions League ban, meaning he definitely misses Juventus' home game against Young Boys on Oct. 2.

Can UEFA extend the ban?

Yes. As stated in 50.01 of the regulations: "In case of serious offences, the UEFA Control, Ethics and Disciplinary Body (UCED) is entitled to augment this punishment."

UCED met on Thursday to discuss all disciplinary matters arising from Matchday 1 of the Champions League and took into account referee Felix Brych's report.

If Ronaldo's behaviour is adjudged to be overly aggressive then UCED could ban Ronaldo for an additional one or two matches. This would mean he could miss one or both of the games against former club Manchester United on Oct. 23 and Nov. 7.

However, ESPN has been told the UEFA charge is purely in relation to the red card and not the time it took him to leave the field of play. As such it is highly unlikely that Ronaldo will receive any extended ban on top of the automatic one-game suspension.

Can Juventus appeal against the red card?

No. Ronaldo will now miss the Young Boys game regardless. There is no right of appeal against "an automatic one-match suspension following a dismissal" in UEFA competitions as shown in regulation 61.1.c.

However, if UCED does give Ronaldo any additional games then Juve could appeal against that portion of the suspension. They will have three days to lodge the appeal after the decision is handed down next Thursday.

Any appeal against an additional suspension will be heard before Matchday 3 on Oct. 23.
