Following permission from the FA, Harry will now stay until the end of the season on a youth loan.
The Gingerbreads Manager Adam Stevens commented "I'm obviously delighted, Harry has been a great asset for us. When we heard that we had a glimmer of a chance of him staying we had to jump on it. I have to thank Grimsby, Pat and the FA"
Harry joined the club in September, making his debut against Warrington Town. He has since made 21 appearances, scoring 3 times for the Gingerbreads.
