There was whispers about Helenius being back out on November. Not sure about Solis. Perhaps Oner is waiting to see if he can get the winner of Wlad/Povetkin before announcing another fight.
Cöckblocked by the K brothers. These guys aren't even trying anymore because they know they wouldn't even get close to a title belt with the brothers around.
Solis just fought Larsen back in April and Saglam in July. He's still looking for a fight though as he is supposed to be high up in the IBF rankings. I think he'll take a couple more Blevel types then push for an IBF eliminator once Pulev has taken his beating.
