Boxer Adam Etches lost his grandfather to cancer just hours before taking part in a charity event for Sheffield’s Weston Park Hospital.
The Birley Bomber - who is back in the ring on Saturday - was told of the traumatic news as he prepared for the fund-raising 10K at Graves Park, on Sunday.
The middleweight is an ambassador for WPH - his weekend show will raise money for their cause.
Speaking before completing the race, he said: “I signed up to do this run, a few months ago, to raise some money and awareness for Weston Park, and it just happens that I lost my grandad this morning, to this shocking disease.
“I need to make sure I put a good time in and do him proud. It was even more reason to come. He’s been suffering for a while, and he passed away on the morning of his run.”
Etches, 24, added: “We’ll be raising a lot of money for Weston Park, on Saturday and I urge everyone to dig deep and raise as much as we can.”
As for Saturday’s combat at the Double Tree by Hilton Hotel, against Argentina’s Victor Jesus Rosales, 29, he said: “I need to go in there and win, the guy is unbeaten. He’s had 10 and won 10, so he is no mug.
“I need to put the record straight and get back on that ladder.
“One day I want to become a world champion and I need to go back to the drawing board and re-build. And that is what I am going to do on Saturday.
“The plan is not to get hit and land as often as I can, rather than concentrating on what I am doing and land big punches all the time. “I’ve changed my way a bit, I will see if I can avoid a few more this time.”
* Four-time World Super Middleweight champion Carl Froch has announced he is retiring from boxing and will join Sky Sports, to work alongside Sheffield’s Johnny Nelson.
Froch has brought down the curtain on a sensational career during which he twice won the WBC title, as well as the WBA and IBF belts. In 35 fights, he was the victor in 33 with 24 by knock out.
His final fight was his most memorable, defeating arch-rival George Groves in a rematch in front of 80,000 at Wembley Stadium.
Froch will now join Adam Smith, former WBO champion Nelson and other expert analysts as part of Sky Sports’ boxing coverage. Fight fans can enjoy up to 120 fight nights over the next six years on Sky Sports including coverage of Sheffield’s Kell Brook, Anthony Joshua MBE, James DeGale and Scott Quigg.
Froch said: “I’m incredibly proud of what I have achieved in boxing but now is the right moment to hang up my gloves. I have nothing left to prove and my legacy speaks for itself. Sky Sports is the home of boxing and has followed me throughout my career. I can’t wait to join the team and help bring fans the best fighters, the best contests and the best analysis. Nothing can replace the thrill of stepping into the ring, but with Sky Sports I’ll be doing the next best thing.”
