The Cheetahs have been dealt another blow with the news that Willie le Roux could face an extended period on the sidelines.

The Springbok fullback is suffering from an ankle injury, and SuperSport is reporting that he could be out for up to five weeks.

Le Roux didn't feature against the Reds last weekend as he was being rested, so it's unclear when he suffered the injury.

His absence would be a major blow for the Bloemfontein outfit, which has already lost Heinrich Brüssow for the season to a broken arm.

Heyneke Meyer will also be closely monitoring the status of the fullback, who was one of the five nominees for World Player of the Year last season as a result of his performances for South Africa.
