Joe, who joined the young Bees in the summer of 2019, will head to Lincolnshire to work under Paul Hurst for the remainder of the campaign to continue his development and aim to get some regular First Team game time.
The 19-year-old has made 49 appearances so far for Brentford B since his arrival from Bury, 16 of which have come this season where he has provided excellent versatility, playing in a number of positions.
The youngster has featured through the middle as a striker as well as across the midfield and occasionally at right back during his time with the B Team. He has also found the net nine times in total.
Joe last featured for Neil MacFarlane’s side on Saturday morning as he played the first 45 minutes in the 2-0 win over Hemel Hempstead Town at Bisham Abbey.
Grimsby are currently 23rd in League Two and Joe will head north with the aim of helping the side to climb away from the relegation places in the second half of the campaign.
Discussing the opportunity for Joe to step out on loan, Brentford B Head Coach Neil MacFarlane said: “This is a terrific opportunity, at the right time, for Joe to go and play in the Football League. He’s been a fantastic leader for us in the B Team, along with many other really good young professionals. It’s been impressive to see players from the B Team like Jaakko Oksanen, Arthur Read, and now Joe, get the opportunity to go on loan in the Football League and I think it reflects positively on the hard work that has been put into our B Team project.
“Joe has done really well for us and he’s played many games. He’s not quite broken into that First Team group as yet, so we all feel it’s the right time for him to step out and play League football where he will, hopefully, get many minutes under his belt.
“I think Joe will be a really useful player for Grimsby because they will have a player who is so versatile. He is super fit, which is one of his assets, his work ethic is incredible, and I think he’ll help the team in whatever position he plays.”
