The captain had been sidelined following title rivals Al-Hilal’s signing of former Real Madrid teammate Karim Benzema, while Al-Nassr faced limits in the transfer market.
Ronaldo quickly reminded fans of his impact, opening the scoring in the 18th minute after Sadio Mane’s precise pass.
He had already threatened earlier with attempts in the first minute and from distance. Al-Nassr, third in the table, remain four points behind Al-Hilal but hold a game in hand.
Ronaldo’s goal marked his 17th of the season, keeping him in the Golden Boot race alongside Ivan Toney and Julian Quinones.
