Joel McIntyre announced his retirement from boxing in the wake of his English title defeat on Saturday.
The Leigh Park light-heavyweight suffered a unanimous decision loss against Watford fighter Miles Shinkwin at York Hall.
That meant El Toro missed out on the vacant English belt he previously held.
In the lead up to the bout McIntyre said he’d walk away from the sport should Skinkwin win the third contest between the pair.
And as the Watford-born boxer ended the rivalry between the two, El Toro has now quit.
Posting on Facebook just hours after the defeat, McIntyre wrote: ‘I came into this professional game almost 10 years ago with 12 amateur fights to my name.
‘Up until early this year I'd fumbled along not listening to anyone and wasting my natural gifts.
‘I hooked up with Daron Wiseman in April and since then that man has changed my game to a ridiculous degree.
‘It just wasn't my night (against Miles Shinkwin).
‘Miles is an old rival and a very slippery customer, not to mention tough as old boots, and he spoiled the party for me.
‘Daniel Iaciofano, Richard Tucker and Daron had me in the best shape, had the game plan down pat but as is very often the case – in the live situation it's just not that easy.
‘Let me tell you the last year of mine and my families lives has been tough to say the very least.
‘Lots of 'friends' lost and some nowhere to be seen, but I feel truly cleansed of all that right now.
‘I am disappointed let me tell you but the relief is real.’
Still only 30, McIntyre can walk away from the ring proud of his achievements.
The Leigh Park fighter finished with a record of 18-4 and beat Shinkwin in Portsmouth to become English light-heavyweight champion in 2016.
And McIntyre says he’s in a good position after retiring from the sport.
Continuing his Facebook post, he said: ‘I’ve tried to do something with my life and I've come up short.
‘But as a former champion of my country, I hang up the gloves and begin my life proper with a new home and a new business and more than a few prospects in my life.
‘That's it for now anyway.
Big love to all that deserve it and thank you.’
