Explained: Why Cristiano Ronaldo isn't playing for Al-Nassr in the Saudi Pro League

Ronaldo was a notable absentee from the Al-Nassr squad for Friday's Saudi Pro League match. The Portuguese superstar has been sidelined after his red card for an elbow last time out against league leaders Al-Hilal. Al-Nassr are also without coach Luis Castro for Friday's fixture as he's been forced to take a break on medical advice.

Ronaldo has been central to Nassr's form this season, enjoying an incredible campaign in which he has scored 36 goals in 37 games in all competitions; he has also registered 12 assists, so his absence is sure to be keenly felt. However, his elbow in the Saudi Super Cup against Al-Hilal has led to a two-match ban, meaning he will also miss next weekend's clash with Al-Khaleej.

Ronaldo is unlikely to be tasting domestic glory this season as Nassr are currently 12 points behind league leaders Al-Hilal. Nassr have lost five games this season; Hilal, by comparison, are unbeaten.

Once Ronaldo's suspension is served, he will be back on the pitch, likely beginning on May 1, when Nassr play Khaleej again, this time in a King Cup of Champions semi-final.
