Rory Finneran made his debut for Blackburn Rovers at the age of 15 in their FA Cup win against Cambridge United.
The youngster was a late substitute in the 5-2 win yesterday.
The controlling midfielder replaced Sammie Szmodics in the 91st minute, who played an important role in the convincing 5-2 win with a hat trick.
Interestingly, Finneran came on without shirt sponsor Totally Wicked. That's a British company that sells vapes.
It is illegal in Great Britain to sell vapes to people aged 17 or under.
