RANGERS striker Alfredo Morelos is set to miss next month's Old Firm derby after being called up by Colombia manager Reinaldo Rueda.

The South American nation face two crucial qualifiers in the qualifiers for the Qatar World Cup, playing Peru on January 28 and Argentina on February 1 - the day before the clash with Celtic.

Morelos hasn't been part of the Colombia set-up since last summer's Copa America and will miss at least two Premiership matches.

Rangers face Ross County on Saturday January 29 and Celtic the following Wednesday and the striker won't be available for either match, while the 25-year-old could also miss the game with Livingston on Wednesday 26 January.

Colombia's star striker Duvan Zapata is unavailable after picking up a stomach injury and will play no part in the upcoming international fixtures.
