Alfredo Morelos is a doubt for Sunday's Old Firm
The striker returned from Colombia duty with a thigh injury
Rangers striker Alfredo Morelos is a doubt for Sunday's Old Firm Derby with Celtic on Sunday.
Morelos picked up a thigh injury whilst away with Colombia on international duty and was unable to play in last week's 3-0 win over Bolivia.
He has since returned to Glasgow to focus on his recovery.
A statement from the Colombia FA read: "The coaching and medical staff of the Colombia Men's Senior National Team reports that, after performing medical examinations on player Alfredo Morelos, a muscle injury to his left thigh was confirmed, which prevented him from participating in the previous commitment against Bolivia and in the same way does not allow him to participate in the next match of the Qualifiers for the FIFA Qatar 2022 World Cup.
"For this reason, the striker is called off to begin his recovery work. We wish the player a good return to his club."
Morelos was substituted in the Gers second leg win over Crvena Zvezda earlier in the month and appeared to be suffering with a thigh problem.
He has scored 12 goals in 26 league appearances this season but has only scored one goal in his last nine appearances.
Rangers host Celtic on Sunday, currently trailing the league leaders by three points.
