Middlesbrough defender Bradley Halliday has signed a one-year contract extension with the club.
The 19-year-old academy graduate is currently on a season-long loan at York City.
"I'm really pleased with progress I have made over the last couple of years and to be offered an extension to my contract is excellent," Halliday told the club's official website.
"I'm really grateful to York for giving me the chance to play. I've played four times for them and got man of the match twice so I must be doing something right."
Boro are back in action on Saturday when they travel to Manchester City in the fourth round of the FA Cup.
