Manchester United have moved quickly to assure fans over an injury collected by Cristiano Ronaldo.
The Portuguese winger had been expected to line up against Glentoran at the Oval, but was conspicuous by his absence as the Reds flew to Belfast on Wednesday morning.
A Club spokesman told ManUtd.com: "Cristiano has been left out of tonight's friendly against Glentoran with a slight ankle knock. He was left in Manchester as a precaution.
"He will train on Friday and is expected to be fit for Sunday's game against Reading."
