Leeds have rewarded defender Sam Byrom with a new three-year contract following the teenager's first-team breakthrough.
Thorp Arch academy product Byrom, 18, has signed a new deal just two days after making his league debut for the club and just several months after being handed his first professional contract.
"I'm delighted," Byrom 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 [pre-season] 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."
Byrom was handed his chance by manager Neil Warnock in the Capital One Cup win over Shrewsbury following injury to Tom Lees.
He then retained his place in the starting line-up at right-back against Wolves on the opening day.
