Leeds United were one of several clubs thought to be keen on the England Under-17s striker.
Hirst - whose dad is former Owls goalscorer David - recently scored twice on his debut for England's Under-17s and was attracting interest from Yorkshire rivals Leeds United, according to the Daily Mail.
A host of Premier League sides - notably Chelsea, West Ham and Newcastle - were also listed as suitors, but the 17-year-old has put those rumours to bed by committing to his boyhood club.
It's fair to say the news has been well-received in the blue and white half of Sheffield, where Hirst senior was a League Cup winner 1991, and scored 32 goals that season as Wednesday returned to the top flight at the first time of asking.
The now 48-year-old was also on target in the 1993 FA Cup final, earned three caps for England and was wanted by Sir Alex Ferguson at Manchester United prior to Eric Cantona's arrival.
Incredibly, though, no-one else seems to have mentioned the D-word... Are we sure they're related?
Oh, who am I kidding... Here's what's being said on Twitter:
