Crocked Alfredo Morelos shouldn't have been allowed to travel for Colombia duty by Rangers, reckons Richard Foster.
The 25-year-old was absent for his side's 3-0 win over Bolivia as he deals with a "muscle overload" while on international duty.
He remains in South America ahead of the clash with Venezuela next week as Colombia look to mount a late push for the World Cup.
With the crucial derby clash with Celtic just around the corner concerns have ramped up the Morelos could be missing for the showdown.
Former Rangers star Foster insists it has been clear since the Europa League clash with Red Star Belgrade that Morelos had a knock.
The Ibrox talisman was replaced in the second half of the last 16 showdown, but was given the nod by Gio van Bronchorst to start against Dundee days later.
Foster reckons Rangers should have told the Colombian FA Morelos wasn't fit rather than leave the player to travel across the globe and deal with a muscle issue.
He told the PLZ Football Show: “You’ve seen it in the last European game.
"He came off with 10 minutes to go, and he was sort of stretching like he was in a bit of discomfort. I was surprised he played against Dundee.
“Rangers are a better side when he plays. I know Roofe and Sakala have come in, but Rangers are a better side when he is in form.
“It’s surprising that he would travel thousands of miles for them to say he has got muscle fatigue. Surely if he has muscle fatigue Rangers have a word with Colombian FA and say ‘we will keep him here and look after him.’
“He’s travelled there, but it doesn’t sound good that he’s there and they say he’s fatigued.
‘It’s not only what you’d miss in terms of productivity, it’s a team player, and someone like Morelos would be a massive loss to Rangers.”
