After losing 3-0 to Queen of the South on Thursday night, Rangers are back in action later today as they host Raith Rovers at Ibrox.
McCall will be hoping to make sure that Rangers get back to winning ways immediately, but looking longer-term, he may have a boost on the horizon.
Back in February, Rangers completed the loan signings of five Newcastle players; Kevin Mbabu, Remie Streete, Gael Bigirimana, Shane Ferguson and Haris Vuckic.
So far, it's been pretty disastrous. Vuckic has been prolific, scoring six goals already, but Streete lasted just 44 minutes on his debut, whilst Mbabu, Bigirimana and Ferguson have yet to even kick a ball for Rangers through injury.
Ferguson was expected to provide width down the left hand side for Rangers, but his absence has been a blow to McCall.
Now, the Rangers manager has told The Scotsman that Ferguson has been back in training with Newcastle - and he's hoping to get a real look at the Northern Ireland international in the coming weeks.
"Ferguson’s had two weeks of training at Newcastle. We had that clarified, it has been two weeks contact training," said McCall. "All I can say is we’ll have a look at him. He had a knee op in October, so I’d imagine if you’ve been out six months it would take you a month to get anywhere near playing games."
"I don’t know the lad but he might come up and join in training and he might be one of these athletes. He might have been doing a lot of fitness work. Until we see him out here, we don’t know."
"Obviously, I got it relayed to me, from a medical point of view, that it might be difficult in a short space of time for him to have an impact. I’ll have a chat with him face to face and we’ll see where he’s at. Again, with the contact it might be ‘just be careful’ or it might be ‘let’s get in about it," he added.
With a play-off campaign on the horizon for Rangers in the Scottish Championship, having Ferguson play any part would be a big boost - but it's only a slim hope right now for McCall.
