"I will tell you this, if he doesn't stop it and we keep on beating him like this he's getting hurt. Why hasn't the referee stopped the fight? I don't get why."
He went on: "Maybe you shouldn't leave it to the referee. But you're not going to take him out to the face, you're going to take him out to the body."
Less than two rounds later, referee Victor Loughlin did eventually call a halt to the fight when Blackwell could no longer see out of his left eye.
The dethroned British middleweight champion collapsed after the results had been read out and was immediately treated by paramedics.
He was taken to hospital having suffered a bleed to his brain but was later reported to be in a stable condition.
Eubank Snr had also repeatedly banged on the canvas in a bid to attract the referee's attention and later said he felt the fight should have been stopped much earlier.
Eubank Snr is himself still haunted by the memories of leaving fighter Michael Watson in a coma 25 years ago.
The high-profile fight was stopped in the final round but, even so, Watson spent 40 days in a coma and had to have six brain operations to remove a blood clot.
Last night's fight saw Eubank Jnr landing eye-catching punches from the off and found it easy to evade Blackwell, who as the fight went on looked more and more like he would need a knock-out to retain his belt. But that never looked forthcoming.
Eubank Jnr appeared as if he was tiring but he did enough in the early rounds to have won on points had it gone the distance.
Blackwell's eye had been closing for a few rounds and blood was coming out of his nose when the referee stopped the fight.
Eubank Jnr said: "I hit him with some big shots, maybe the referee should have stopped the fight earlier. This is what boxing needs, two warriors who stand and fight.
"I have respect to anyone who steps in the ring. It's sad that he had to leave on a stretcher. All I wanted was his belt and I've done that. I've achieved my dream of becoming a British champion."
