Alongside their ratings from the pound for pound top 50, the likes of DeGale, Groves and Abraham are looking over their shoulder as a crop of hungry fighters eye spots in the top five.
Here’s the top 10 as it stands (P4P rating/record):
1. James DeGale (34 / 23-1-1)
DeGale takes top spot on the strength of his current opposition and a credible draw with ex-number one Badou Jack.
2. Gilberto Ramirez (40 / 35-0)
The Mexican is much-touted as the future of the division but just needs to defeat another of the names around him in order to reach the summit.
3. George Groves (48 / 26-3)
Groves salvaged his career with a win over Fedor Chudinov and is rightly recognised as a major player at 168.
4. Arthur Abraham (NR / 46-5)
Been there, seen it and done it. Abraham still wants to prove he can hang with the top guns against Eubank Jr. next month.
5. Anthony Dirrell (NR / 30-1-1)
Has taken knocks but always returns stronger. Another world title reign seems likely in the future.
6. Andre Dirrell (NR / 26-2)
Resilient like his brother and on the verge of having another chance at a world ruler.
7. Tyron Zeuge (NR / 20-0-1)
The unknown quantity of the ratings and needs to fight outside Germany in order to fully prove his worth.
8. Julio Cesar Chavez Jr. (NR / 50-3-1)
Form prior to his move down to 164 pounds in losing to Canelo Alvarez keeps the Mexican rated ahead of a rumored return to the weight class.
9. Chris Eubank Jr. (NR / 24-1)
A new force at the higher limit having been defeated by Billy Joe Saunders in his toughest test at 160.
10. Callum Smith (NR / 22-0)
The contender making the most noise and a boxer who can announce himself on the world stage with a WBC title win this coming September.
