Hylton in loan switch
"Young Danny has now got himself in good shape," he told the club's website.
"We've given him a little taste of first-team football in recent weeks and now he needs to have a run of consecutive first-team matches which hopefully will see him back here competing for a place."
A close-season signing from Aldershot, Hylton made his Millers debut as a substitute in the 1-0 victory at Brentford and was handed his first competitive start in the Football League Trophy win at York City last week.
He will now be looking to get more action at the Lancashire club, who yesterday parted company with manager Kevin Blackwell after a poor start in League Two.
