Cowley told The News: ‘Joe was given a slightly extended break, just because he’d had such a busy summer with Wales.
‘He broke his toe, but it was a clean break and he’s fine. He will be able to train with padding.
‘With Denver and Reeco, we hope to see them by the middle of pre-season. They should be training with the group in Spain again, all being well.
