Whilst the Middleweight division doesn't appear to have much depth in terms of contenders it does have some really interesting fighters rising through the ranks right now, and they are a very varied bunch of fighters from all over the globe.

For those who missed our looks at the champions and contenders at Middleweight those were covered here:
The state of the Division - Middleweight - The Champions
​The state of the Division - Middleweight - The Contenders
 
Christian Mbilli (13-0, 13)
One of the best prospects in world boxing, regardless of weight, is Cameroonian born French fighter Christina Mbilli, who is looking like one of the most outstanding Middleweight hopefuls out there. He was a stellar amateur, winning gold medals at the European Youth, European Union and European Olympic qualifiers, and competed on the WSB. Since turning professional less than 2 years ago he has ripped through his competition, stopping his 13 foes in just 38 rounds. His competition hasn't been the strongest, but he has taken the unbeaten record of Ramon Aguinaga and smashed through Mexican Luis Fernando Pina. At 23 years old he should be regarded as one of the hottest fighters in professional boxing and someone to seriously keep an eye on.
 
Serhii Bohachuk (12-0, 12)
We know how there's a Ukrainian take over of boxing with the likes of Vasyl Lomachenko, Oleksandr Usyk and Oleksandr Gvozdyk all holding world titles and all set out to prove they are. There is also a second wave of Ukrainians below those top tier fighters, and including in that is 23 year old Serhii Bohachuk. The youngster made his debut in early 2017 and has gradually stepped up his competition, whilst running through fighters. Dubbed "El Flaco" he is certainly explosive and appears to have no issues making Light Middleweight, at the moment, but clearly has the frame to fill into a very strong Middleweight. A long term prospect, but one well worthy of attention.
 
Kazuto Takesakao (10-0, 10)
Japanese Middleweight champion Kazuto Takesako isn't the next Ryota Murata, but the 27 year old is a legit prospect, and a really heavy handed, aggressive and exciting fighter, who usually comes forward, and always throws with bad intent. His KO win over Shoma Fukumoto was a big coming out win, and since the he has won the Japanese title and defended it once, with his next defense set for March. There are technical issues he needs to sort before progressing beyond regional level, but he has suggested that he wants to unify the Japanese title with the OPBF and WBO Asia Pacific titles, so it's clear that he's looking to make gradual steps upwards, towards a world title fight. One to watch, but not one who will be in the world mix in the next 12 months.
 
Meiirim Nursultanov (10-0, 8)
The 25 year old Meiirim Nursultanov is one of two notable Kazakh prospects at Middleweight, and is probably the better of the two, if we're being honest. The Oxnard based, Klimas managed fighter turned pro in late 2016 and has been moved gradually through the rankings, with his best wins coming in his last 2 bouts. In late 2018 he stopped Jamar Freeman and began his 2019 with a win over Ramon Aguinaga. He's young, very powerful, and has been sparring with top competition, helping develop his skills, though he is still some way from a big fight of his own.
 
Misael Rodriguez (8-0, 4)
Talented Mexican Misael Rodriguez won a bronze medal at the 2016 Rio Olympics and is tipped to turn that medal into professional titles under the guidance of Abner Mares and Richard Schaefer. The talented 24 year old debuted in 2017 and although easy so far he is a fantastic talent who is getting experience and being developed by a fantastic team. Although talented it's unclear how talented he is given the level he's been fighting at, but given his amateur credentials and the team involved with him it's hard to not be excited about him. Sadly he appears to be a long term project, and it could be 3 or 4 years before we see him in really meaningful fights, though he is scheduled to fight just hours after this article goes live.
 
Artem Chebotarev (6-0, 4)
At the age of 30 Russian fighter Artem Chebotarev will need to make a big step up this year, but he did show signs of doing that last year, so we will give him the benefit of the doubt. He was a stellar amateur, winning a gold at the European Championships in 2010 and a bronze at the 2013 World Amateur Championships. He won the APB title in 2016, and scored notable wins in both the APB and the Amateurs. Sadly those side ventures meant he didn't make his "proper" professional debut until January 2017. In his debut year he went 4-0 (3) and scored a notable win over Nuhu Lawal. He built on that start in 2018 and ended the year with a big win over Javier Francisco Maciel, though did lose 12 months out of the ring. If he can score 1 or 2 big wins this year he will certainly be in the title mix by the end of the year.
 
Ulugbek Khakberdiev (5-0, 3)
Unbeaten Uzbek hopeful Ulugbek Khakberdiev has had a frustrating career so far. He turned professional in 2017 and beat Karen Avetisyan, a very under-rated journeyman. He really came to our attention in September 2017, when he stopped Dmitry Sukhotsky, in what should have been a huge break out win, but he would then have a break from the ring losing momentum and not fight for over 7 months, before picking up a low key win in Uzbekistan. Sadly he's again been inactive, and hasn't fought since May 2018. Given how talented, promising, heavy handed he is there is so much to be excited about, and at 26 he does have time on his side, but needs to get active after essentially wasting the last year and a bit. He's too good to not fight, but it appears there is something keeping him inactive, and that is a huge shame during what should be the start of his prime years.
 
Janibek Alimkhanuly (4-0, 1)
Whilst top Uzbek amateur fighters have taken immediately to the pros, some of the top Kazakh amateurs have taken a few fights to adapt. It appears another Kazakh who hasn't quite settled to the professional style yet is the unbeaten Janibek Alimkhanuly, who looks to have the tools to go a long way, but just needs a little bit of time. As an amateur he won the World Amateur Championships, the Asian Championships, twice, and competed at the Olympics. As a professional his career has been stop start, but he's now based in the US with Top Rank and has fully committed to being a professional boxer. He's notched recent wins over tough competition, in the form of Carlos Galvan and Vaughn Alexander and we're expecting to see him really spread his wings in 2019, with some top performances as he continues to adapt to professional boxing.
