London - British heavyweight boxer David Haye will donate 10 percent of the ticket sales from the second fight of his comeback to stricken middleweight Nick Blackwell, he announced on Wednesday.
Blackwell, 25, has been in an induced coma since collapsing at the end of his British middleweight title defeat by Chris Eubank jnr on Saturday.
Haye will fight unheralded Kosovan Arnold Gjergjaj at London's O2 Arena on May 21 in his second fight since coming out of retirement and revealed that a portion of the money raised by ticket sales will go to Blackwell.
"Nick is only in that situation because he's so tough and is one of those boxers who goes out there and puts it on the line," Haye said.
Former world heavyweight champion Haye, 35, returned to the ring in January after a three-and-a-half-year absence and recorded a first-round stoppage victory over Australian Mark de Mori.
Gjergjaj, 31, is unbeaten in 29 fights, but has only once fought outside Switzerland, where he is based.
"My comeback fight was a big success in my eyes and next up I wanted an opponent who is bigger than me, undefeated and is fast and can move," Haye said.
