Cristiano Ronaldo will make his Al Nassr debut next Sunday, but he will do so without team-mate David Ospina, who fractured a bone in his elbow on Saturday.
Al Nassr are preparing for Ronaldo's Saudi Pro League bow at home to Ettifaq in their next match.
But they head into that January 22 game on the back of a goalless draw at Al Shabab.
Although the result maintained a three-point gap between league leaders Al Nassr and their third-placed hosts, it came at a cost.
Goalkeeper Ospina, who starred in Europe with Nice, Arsenal and Napoli, faces six weeks out, the team announced.
Ospina has been a key part of an Al Nassr defence that has conceded a league-low six goals this season. Only Al Shabab's Kim Seung-gyu can better his seven clean sheets.
