Northampton Town have signed Brighton's George Cox on loan for the rest of the season after the left-back's recovery from heart surgery.

The 20-year-old - who is yet to play for Brighton's first team - had an operation last summer after screening found he had an irregular heartbeat.

Cox has since returned to playing and training with their under-23 side.

"He has a lot of talent and ability and he needs to be out playing senior football," said Town boss Keith Curle.
