Teenage defender Sam Byram has committed his future to Leeds United by putting pen to paper on a new three-year contract at Elland Road.
Byram only signed his first professional deal at the end of last season but has since made his senior debut for the Whites in their 4-0 Capital One Cup triumph over Shrewsbury.
He also played the full 90 minutes of Saturday's Championship opener at home to Wolves, which Neil Warnock's side won 1-0.
The 18-year-old has now signed a new deal to keep him at the West Yorkshire club until 2015.
"I'm delighted," Byram, who has featured heavily for Leeds over their pre-season, told the club's official website.
"I didn't expect anything like this at all when we started back six or seven weeks ago."
"I was in the squad for the Farsley (friendly) game and I just wanted to do well and impress the manager.
"We went on the tour after that, but I didn't expect to be involved when we came back.
"I know some of the young lads took part in the tour last season, but didn't go out to Norway and play in the other games after they got back. I thought that would be the same with me this season.
"But it's been good. I played a part in every game. The manager and the staff have been really encouraging, and they said they've liked my attitude."
Byram admits it came as a surprise when he was told he would be making his senior debut against Shrewsbury.
He added: "Tom (Lees) got injured and I was told on the Friday I would be playing.
"I was nervous all night and in the morning, but once I got in the tunnel I was alright.
"I thought Leesy would be back on Saturday for the Wolves game, but being told I was playing and knowing that the gaffer trusted me to play was a big boost.
"My aims are still the same as they were over the summer in that hopefully I can play as much as possible and be involved."
