Nottingham Forest have been dealt a "massive blow" with the news that Nathan Tyson is expected to be out for a month through injury.

The pacy forward suffered a calf injury in training at the end of last week which ruled him out of the trip to Cardiff.

It is bad news for Reds boss Billy Davies, who is already without strikers Dexter Blackstock and Robert Earnshaw.

"It is a massive blow to lose Nathan for a month," said Davies. "To lose the pace of Tyson and the goalscoring of Tyson, along with Blackstock and Earnshaw, means we have got key players missing from the squad.

"As I have said before, top teams can't afford to lose important players. The Bristol City game on Saturday might come too early for Dexter Blackstock, while Earnshaw is probably looking at Middlesbrough after the international break."
