Rangers star Ryan Jack has been sent home from the Scotland camp after picking up an injury.

The on-form midfielder has been impressive for his club so far this season but has been ruled out of this evening's must-win Belgium clash.

Gers boss Steven Gerrard has previously admitted Jack would be one of the first names on his team sheet such is the form he's found himself in.

Which is a blow for Scotland manager Steve Clarke who needs a result against the Red Devils this evening to have a chance of making it out of Group I.

The Scots head coach confirmed the news and revealed it was a precautionary measure.

He said: "Ryan has gone back to Rangers.

"He had a little bit of swelling on his knee on Friday and was prepared to sit on the bench.

"But on Saturday there was more swelling and Rangers decided to go safety first."

Steven Naismith has also been ruled out.

Scotland are hanging by a thread after Friday's 2-1 defeat to Russia at Hampden.
