“We are hoping to get him some time this block but he is travelling in the right direction,” said Sherratt.
When asked whether he would have to play for Cardiff before being considered for Wales, Sherratt responded: “That will be up to the Welsh selectors, it will be when he is ready.
“Sometimes a second row or back row can come back at 90%, but with wings in particular, when your attributes are based on power and speed, it’s very difficult to come back unless you are 100%.
“Josh has had a long time playing at 90%, so for him it’s important when he comes back he wants to be 100% ready.
“Hopefully that is before the end of this block, and if he is back he will be in contention for Wales because he is a quality player.
“But also I do know for Josh, we have looked after him, he has had a summer to recuperate and he wants to pay Cardiff back.
“Josh’s priority will be to play for Cardiff and off the back of that to play for Wales.”
