Caretaker manager Gradi believes the 22-year-old striker could develop into one of the club's best players.
"Shaun needed that break and hopefully this will help him," said Gradi. "I keep saying that he is potentially the best goalscorer we have at this club.
"I wish I had a fiver for every time I said it but it's up to him to prove that to me right now."
Gradi added: "A few years ago the fans would have enjoyed that but these days they aren't happy unless you are winning. I can't guarantee that we will win games but I can promise that we will try our best."
