Harry Gray made his debut for Leeds United`s first team on Monday, watched by his great-uncle, a club legend.
The 16-year-old was substituted for Brenden Aaronson in the 86th minute of the match against Stoke at Elland Road, with Leeds leading 6-0.
This debut makes him the youngest member of his footballing family to play at the senior level.
Harry is the younger brother of Archie Gray, who moved from Leeds to Tottenham for £30 million last July.
Their father, Andy, and grandfather, Frank, also played for Leeds.
His great-uncle, Eddie Gray, is a legendary figure at the club.
Eddie Gray, who played 532 times for Leeds and managed them for four years, was in the stands on Sunday to witness Harry`s debut.
He appeared to be deeply moved as Harry entered the game for the first time.
Leeds` 6-0 victory over Stoke has significantly boosted their chances of returning to the Premier League, with only two games remaining in the season.
The team secured promotion to the top division after Burnley defeated Sheffield United 2-1 later that evening.
