Blue-chip light heavyweight prospect Oleksandr Gvozdyk has been added to the HBO PPV card headlined by the junior welterweight world title unification bout between Terence Crawford and Viktor Postol on July 23 at the MGM Grand in Las Vegas, Top Rank announced on Friday.Gvozdyk (10-0, 10 KOs), a 2012 Olympic bronze medalist from Ukraine and one of the top prospects in boxing, will take on Tommy Karpency in a scheduled 10-round bout.Gvozdyk, 29, was supposed to box Robert Berridge in an untelevised bout on Top Ranks card on July 16 in Lancaster, California, but he was moved to the pay-per-view card a week later against Karpency, a better-caliber opponent than Berridge.The opening on the pay-per-view telecast came about because super middleweight titlist Gilberto Zurdo Ramirez tore the tendon around the knuckle of his middle finger on his right hand during a sparring session on Tuesday, forcing his first defense against Dominik Britsch to be canceled. That fight was supposed to be the co-feature on the July 23 card.So the vacant featherweight world title bout between Oscar Valdez (19-0, 17 KOs) and Matias Adrian Rueda (26-0, 23 KOs) was elevated to the co-feature position, welterweights Jose Benavidez Jr. (24-0, 16 KOs) and Francisco Chia Santana (24-4-1, 12 KOs) will meet in a 10-rounder and Gvozdyk-Karpency will open the broadcast.Karpency, a 30-year-old southpaw from Adah, Pennsylvania, has faced several quality opponents, including in a pair of light heavyweight world title bouts. Two fights ago, last September, Karpency got knocked out in the third round by world champion Adonis Stevenson, and in 2012 he lost a shutout decision to then-titleholder Nathan Cleverly.In October 2014, Karpency scored the biggest win of his career, a 10-round split decision in a major upset against faded former light heavyweight world champion Chad Dawson.Top Rank wants to measure Gvozdyks performance against how Karpency (26-5-1, 15 KOs) did with other quality opponents while also getting him his first major television exposure.My matchmakers say this is a real test for Gvozdyk, Top Rank promoter Bob Arum told ESPN.com. Karpency was the best opponent we could get on short notice, but we were told he was training for another fight. So this is a good test for Gvozdyk to prove to us that he is as good as we think he is.Ramirez (34-0, 24 KOs), meantime, underwent what Top Rank and adviser Sean Gibbons termed successful surgery to repair his torn tendon on Friday in Los Angeles. According to surgeon Dr. Steven Shin, Ramirez is expected to be out of action for five months. Cheap Stitched NBA Jerseys . Listen to the game live on TSN Radio 1050 at 7pm et.

Sam Burgess believes the lessons learned from his controversial spell in rugby union will stand him in good stead when he returns to the rugby league international scene later this month.The 27-year-old South Sydney forward will return to the England team - following a three-year absence - as captain for the Four Nations Series and says he will be better for his experience in the 15-man game.Burgess, a big-money buy for Bath in 2014, spent just 11 months in the 15-man code as a beacon for criticism while winning five caps for England under Stuart Lancaster before cutting short his stay in favour of a return to the Rabbitohs.Burgess admits rugby league is where I belong after coming through a full season in the NRL, but insists his time in rugby union was a great experience.Its good to be back with the English league team but I also had a great time with the English rugby union team as well, Burgess said on Monday.People have an opinion of what it was like but people within knew what sort of environment we were in.For me I dont have any regrets or anything, Im just looking forward to getting back in an England rugby league jersey and doing my best for my country again.To be honest I didnt really take a great deal of notice about what was going on around me (in rugby union).I was so foocused on what I was doing at the time.dddddddddddd. I wasnt exposed to what was going on so much. Nothing really affected me at all.I took a lot of character out of it, I learnt a lot.I learned probably a lot more about what it took to be successful, to be disciplined and to achieve certain goals. I learned a lot about personal character and team environment.Burgess got the nod to succeed the injured Sean OLoughlin ahead of Canterbury skipper James Graham.(Burgess is) very worthy of the position. He leads from the front, Bennett said.Burgess, who led South Sydney in 2016 when Greg Inglis was absent through injury or representative duty, is over the moon and says hell realise a childhood dream when he leads out a team that is expected to include his twin brothers Tom and George.Graham will captain England in their warm-up international against France in Avignon on Saturday as Burgess serves a one-match ban carried over from his last match of the NRL season.Burgess will make his eagerly-anticipated return in Englands opening Four Nations clash against New Zealand at Huddersfield on October 29 and he admits he has some unfinished business against the Kiwis.
