Lock Bradley Davies doubt is out of Wales tour to South Africa

Lock Bradley Davies will miss Wales' two-Test tour to South Africa in June because of a hamstring injury.

The Cardiff Blues lock, 27, who is heading to Wasps, suffered the problem in training and has undergone surgery.

Meanwhile, Racing Metro flanker Dan Lydiate is out of Friday's Wales Probables v Possibles trial in Swansea.

But Lydiate's hamstring strain is not expected to rule him out of the tour, which starts with a warm-up against Eastern Province Kings on 10 June.

Wales face the Kings in Port Elizabeth followed by the Springboks in Durban on Saturday, 14 June and again in Nelspruit a week later.

In Davies' absence, Alun Wyn Jones and Luke Charteris have been picked at lock for the Probables, while Jake Ball partners Ian Evans in the second-row for the Possibles side at the Liberty Stadium on Friday.
