The 19-year-old’s new deal sees him commit his future to the Tigers until at least the summer of 2020.
A versatile player capable of operating as a centre-back or in a central midfield role, McKenzie first joined the Club’s Academy set-up at the age of nine.
After progressing through the youth ranks to sign a two-year Scholarship deal in March 2015, McKenzie put pen-to-paper on his first professional contract with the Club on his 17th birthday in September 2015.
Despite only being a first-year scholar, McKenzie made 14 appearances at Under-23 level in 2015/16, during which the Development Squad reached the Premier League Cup final, and has since gone on to establish himself as a key member of the Under-23s’ squad over the past 18 months.
He made his senior debut for his hometown Club against Doncaster Rovers in the Carabao Cup earlier this season, playing the full 90 minutes as a young Tigers’ side – that featured six other debutants – slipped to a 2-0 defeat at the Keepmoat Stadium.
Speaking after signing his contract, McKenzie said: “It’s nice to have that little bit of reassurance that comes with signing a new deal, but the hard work still continues and the goal of getting in the first-team remains the same.
“It’s great to see that the Club have shown faith in me by handing me a new two-year deal. The aim now is to repay that faith and really kick on.
“Seeing the likes of Jarrod and Max being given chances to step up and show what they can do has been great to see.
“It shows that there is a pathway from the Academy to the first-team and that is a huge positive for every player involved in the Under-18s and Under-23s at the Academy.
“It shows that if you put in the hard work and are willing to graft in order to progress, then you will be rewarded.
“The dream is to play for my hometown Club. Having been here since the age of nine, getting in the first-team here would be a big achievement.
“As I say, there is still plenty of hard work ahead of me to make that happen but I have belief in myself and my ability.”
