He has joined for one month initially, but that could be extended until the end of the season.
Academy director Dave Wright said: "I think Scunthorpe have kept an eye on James following his first spell there and they have seen him continue his progression.
"We are happy to let him go even though the under-21s have some important games coming up.
"They will miss him, but we won't keep James back just for that reason.
"This move is the right thing for him at this stage of his career."
