Saul replaces Ruiz in Spain squad for Norway, Malta games
The decision was taken after Napoli's midfielder Ruiz underwent tests in a hospital in Madrid earlier on Monday due to a fever which left him out of the Italian club's latest Serie A tie against Udinese on Sunday.
Saul, of Atletico Madrid, will now form part of the squad that will host the Norwegian side in the Mestalla before facing Malta at the National Stadium in Ta' Qali, on March 26.
The Colchoneros midfielder has collected 15 caps for La Roja so far, scoring two goals in the process.
Meanwhile, Real Madrid player Marcos Asensio was reportedly not present in their first training session as he completed a separate training programme which included some gym work and physiotherapy.
