Sky Blues goalkeeper Magnus Hedman has suffered a knee injury and will be out of action for at least a month.

The Swedish number one has been forced to have a scan on the injury which he suffered during last week’s international with Slovakia, when he twisted the knee and damaged his joint.

Sky Blues boss Gordon Strachan has been given permission to sign another Premiership goalkeeper on loan to cover what is becoming a keeping crisis.

Chris Kirkland, who made his debut last week against Spurs will take the gloves for the next game, against Chelsea.

He will also have to face the striking power of Sunderland, Manchester United and Liverpool in the coming weeks.

It will be a big challenge for the player, who was recently called up to the England under-21 squad.

But third choice keeper Morten Hyldgaard has recently undergone a toe injury, and will not be available to cover.

This leaves just Gary Montgomery, a youth team player, to fill Kirkland’s place on the bench.

Normal Premiership rules prevent loan deals between clubs, but Strachan has been given permission to fill the gap.

David Thompson has returned from a trip to Amsterdam, where he had more treatment on the hamstring injury that has been causing him bother since the summer.

Meanwhile Ysrael Zuniga has been dropped from Peru’s team following a disappointing sequence of results.

A new coach has swept out the foreign-based players, leaving Zuniga free to concentrate on his performance at Highfield Road.
