London - Nick Blackwell has ruled out resuming his professional boxing career on Tuesday, despite making progress since collapsing shortly after his defeat to Chris Eubank Jr on March 27.
The 25-year-old was placed in an induced coma and was found to have suffered a bleed on the skull, although he is recovering well and woke a fortnight ago.
When asked on Twitter if he would want to return to the ring, he wrote: "No. that's me done.
"I can't put my friends and family and self through that again but I'll still be involved (in the sport)."
Blackwell lost the British middleweight title bout to Eubank Jr after being stopped in the 10th round.
Eubank Jr, the son of former world champion Chris Eubank, wrote to Blackwell that he had been trying to reach him, and hoped that there were no "hard feelings".
Blackwell replied: "Hello bro no hard feelings, we were both there doing a job and it was unfortunate for what happened but I hope your OK champ."
