Carlisle United have completed the signing of Millwall defender James Brown.

Brown, 19, joins the Blues on a "window-to-window" loan deal which will keep him at Brunton Park until January.

Dover-born Brown signed for the Lions as a schoolboy and made his debut for Millwall in October 2016 in a 2-1 EFL Trophy victory over Gillingham.

"James is someone we’ve known about for a while and he’s another young player who we feel will add to the group," manager Keith Curle said.

"He is very highly thought of and he’s at a point where he needs to develop a profile within the game.

"He can play on the left or right at the back and he’s a player who likes to defend.

"His manager [Neil Harris] wants him to be tested in a competitive first-team environment and this is an opportunity for him to come here and show people that he’s ready to take another step."

Curle revealed at his weekly press conference that Brown had been training with United and the defender will help to provide cover in full-back areas, which is an area the club had been looking to strengthen in.

"We’ve had him with us this week, we’ve liked what we’ve seen and he’s already fitted in well," Carlisle's manager added.

"He’s adjusted to the tempo we train at and the group have accepted him into the fold, which is extremely important.

"He adds more options and I’m sure he’ll be pushing to get the pitch time he needs so that he can really start to kick on."

Brown will wear the number 17 shirt. The deal is subject to clearance of all relevant paperwork.
