Barnsley have signed goalkeeper Nick Townsend on a three-year deal.
Birmingham City shot-stopper Townsend initially joined the Reds last month on a youth loan until November.
But boss Lee Johnson was keen to sign the 20-year-old on a permanent contract before the transfer window shut tonights.
Townsend made his debut for Reds in a their thrilling 7-6 penalty shootout victory away to Scunthorpe United in the Capital Cup first round last month.
But the former Lincoln City loanee has yet to make his debut in League One for Johnson’s side.
Former Sheffield Wednesday keeper Adam Davies has started every league game for the Reds this season and will want to retain the number one jersey.
But Townsend is hopeful of getting his first team chance if he continues to work at his game – and he believes Barnsley is the best place to do that.
"This is a remarkable opportunity for me to progress at a big club in a very competitive league,” said Townsend.
"I've been very impressed with the quality of the players recruited.”
