The sportsman, 25, was taken to hospital after the British middleweight title contest was stopped in round ten.
Blackwell woke from the induced coma on Saturday and by Sunday was talking to family and friends at his bedside, promoters Hennessey Sports yesterday said.
They also revealed Blackwell had suffered a bleed on the skull and not the brain as initially reported. In a statement the firm said: “It was the outcome everyone had been hoping and praying for; Nick had won his toughest fight yet...He’s a fighter. He’s a warrior. He’s a true champion and gentleman. “On behalf of Nick, his family, and very close friends, we’d like to thank everyone for their continued support and well-wishes. It has been overwhelming at times and has certainly not gone unnoticed.”
The referee stopped the fight on 26 March after the advice of the doctor, who said Blackwell was unable to continue because of swelling over his left eye.
Blackwell was carried from the ring on a stretcher and taken to St Mary’s hospital in London.
During the fight, Chris Eubank Sr had urged his son to avoid more blows to Blackwell’s head.
