Dyer told whufc.com: "I am hoping it will help him a great deal. He is chomping at the bit. He is at the age now where he wants to play. He has represented his country, he has captained his country.
"At this present time he isn't going to get in the first team here and he needs to play first-team football or be around the first time squad. Hopefully that will serve him well and he will come back a better and stronger player.
"Josh has been away now for his third month at Cheltenham. He is doing well. He is a young lad and this experience for him will be good. When he comes back hopefully he will feature in the reserves and push on to the first team."
