Leicester City have loaned former Manchester United youngster to Rotherham for a month, before the loan window shut yesterday.
Lawrence was one of two young United players given the platform to shine during Ryan Giggs brief spell as caretaker manager at Old Trafford at the end of last season.
He and James Wilson started against Hull in May, with the Welsh connection further highlighted when Giggs brought himself on for Lawrence in what would be the United legend's last ever playing appearance.
However, while Wilson scored a brace and impressed enough to stay in Louis van Gaal's first team plans, Lawrence was sold to newly promoted Leicester City, who themselves have a strong collection of former United youngsters, many of whom are now first team players for the Foxes.
At 20, Lawrence still has plenty of time to acclimatise to the Premier League, and is almost certainly closer to first team football at the King Power Stadium than he would have been at Old Trafford.
It is looking like the forward has had to go out on loan to another struggling Championship side in order to get the first team football that could cause him to catch Nigel Pearson's eye, much like he did while on loan at Yeovil last season.
Lawrence is joined by two other's with United connections at the Millers, with Scott Wooton arriving from Leeds until January 10, and Reece James also taking in a temporary switch away from Louis van Gaal's side.
