Haskins was awarded the belt after Randy Caballero was stripped of his title after weighing in five and a half pounds over the limit for last Saturday's fight, which had been due to take place at the Mandalay Bay Hotel.
Bristol-based manager, Chris Sanigar, told BBC Points West about his future hopes for 32-year-old Haskins.

Joedyn Luben, 32, had £77,000 in a safe at his home in Penlan, Swansea, he told Cardiff Crown Court.
He claims officers from South Wales Police stole £30,000 of this during the raid in April 2011.
Det Sgt Stephen Phillips, 47, of Swansea, Det Cons Christopher Evans, 38, of Llangennech, and Michael Stokes, 35, from Glynneath, deny theft.
Mr Luben told the court on Tuesday he gave the code to the safe to Det Con Stokes when asked by the officers.
He said he had been saving the money since he was 16 and last used the safe the night before the raid, when he deposited £12,000 following the sale of a car.
No action was taken against Mr Luben so a cheque was written for him to return his money.
However, he said this was £30,000 short of what was seized.
The case continues.

Lyon's president said on Twitter the club were investigating the incident.
Lille have since confirmed their home match against Lorient on Saturday will be free for all women, saying: "Ladies, you are welcome with us."
Lyon's women's team have won the French title 14 times and their captain Wendie Renard highlighted the banners on Twitter, saying: "Lyon supporters... can you give me an explanation for that banner? The men at the stadium, the women in the kitchen?"
Club president Jean Michel Aulas replied: "The club will get tough and will file a complaint against the creator of this banner."
Lyon, who are fourth in the league, lost the match 2-1 at Parc Olympique Lyonnais.

Lallana struck in the 95th minute to seal a 5-4 win moments after Sebastien Bassong had equalised for the Canaries.
Klopp was swamped by his players - and his trademark specs slipped off.
"I have a second pair of glasses, but I can't find them," said Klopp. "It's hard to find glasses without glasses."
Klopp has broken his glasses before during a match, with that pair residing in his former club Borussia Dortmund's museum.
"We won for the first time against Bayern Munich and Nuri Sahin broke my glasses. Today it was Adam Lallana," he added.
Read about how the dramatic game unfolded
Klopp may have been smiling at half-time but just moments earlier he was fuming at his players for allowing Bassong to make it 4-4.
The Reds' defending had been particularly poor throughout, with Norwich having scored from every shot they had on target to lead 3-1.
"There was about 70 minutes that were really good," said the 48-year-old.
"Conceding four goals is in general not good. Conceding from set plays is the biggest rubbish ever because it is too easy for the other team.
"Usually we concede from a corner but now it was from the second ball - we were like rabbits in the headlights, but we won the game in the end."

Klopp was not the only person who felt his side should have defended better in the game.
"I am not happy obviously," said Norwich boss Alex Neil.
"The game was in our hands at 3-1 but after that we managed to turn a really good performance into a bit of a shambles."
