KZ said he would like to get a fight scheduled in about a month. Swanson/Stephens and Lamas/Dias are both at the end of June. It's unlikely he will fight any of them unless one of them come out of their fight unscathed.
Siver probably won't get booked until after his suspension. Does anyone remember how long he was suspended for? I don't remember, but I would assume either 9 months or a year.
What about Nik Lentz? Or a Poirier rematch? KZ is coming off a loss, so how about Elkins?
If it were me, I'd either do the Poirier rematch or since he is coming off a loss, have him fight down to Max Holloway, who is coming off a win. That could be a fun fight and a tune up fight for KZ, and it gives Holloway a fight against a bigger name.
