David Avanesyan, the dangerous 33-year-old Russian, is the bogeyman of the welterweight division.
Eubank Jr, 31, will make his comeback at Wembley Arena in London on October 2.
Avanesyan will be a part of the supporting act, as he puts his title on the line against mandatory challenger Taylor, following his crushing sixth-round knockout of the previously unbeaten Josh Kelly at the same venue on February 20.
The 33-year-old Avanesyan has had difficulty trying to find opponents willing to fight him in the ring, but he will face a live underdog in the form of Taylor, who is currently on an incredible 13-fight unbeaten streak.

'After this, I want a big fight, and a world title'
"I don't understand why Jordy Weiss didn't take this fight," Avanesyan told GIVEMESPORT.
"Liam Taylor is number three I think for my title.
"My manager told me this French guy doesn't want the fight, your next opponent will be Liam Taylor, I said, 'Okay, I need to fight, it's been five or six months after fighting Kelly.'
"Now my focus is on October 2. I need to win. I have given everything to win this fight.
"After this, I want a big fight, and a world title, understand? I will have fought at European level five times.
"I want a world title in my next fight. I want big names. I believe I will get a big fight soon."
'He's a bit of an avoided man'
Avanesyan has returned to Newark to finish his training camp after spending some time in his native country of Russia.
"Yeah, I mean obviously it is frustrating because we feel like he should be pushing on now," Avanesyan's trainer Carl Greaves told GIVEMESPORT.
"Obviously he's won the European title, he's defended it three times, so yeah, he's a bit of an avoided man.
"Who is going to want to take on David Avanesyan? He's flying high, he's in the form of his life, he's high risk, probably low reward for some people.
"But the thing we've got to do is we've got to get in that mandatory position.
"I think we're No. 5 across the board in all the world organisations so I think he can't be avoided if he gets to that mandatory position.
"I think the only way to get to a mandatory position is to get a final eliminator for a world title, win that, and then obviously get the world title fight."
'Eddie Hearn said he's not ready for David'
Greaves also claimed that Eddie Hearn has told Conor Benn to stay well away from Avanesyan.
He added: "Listen, Conor is a fighting man.
"Well, he talks like he's a fighting man, so I presume he is one, but whether he wants David or not I don't know.
"I know his trainer Tony Sims, he don't want David, I know Eddie Hearn said he's not ready for David, he wanted a couple more fights.
"So that's the reason why we're in this position defending the European title against Liam Taylor.
"Fair play to Liam Taylor, he's stepped up to the plate, shown balls that many other fighters haven't got, so you've got to give him massive respect.
"Like I say, he's a good fighter, he deserves his opportunity.
"Whether he'll be good enough or not, I don't know, David has proven he is above European level, so we'll see."
