Hey weight a minute

I think I'll go to non-existent hell for my punny headline, but I got a question: Gleison Tibau and Lil' Heathen Stephens both missed weight for their fight tomorrow. They agreed to a catchweight. Are either of them going to be punished for not meeting their contractually-obligated weight? Is there a standard catchweight clause in contracts? Do either have to forfeit some of their purse?
Seems just as unprofessional as Ryan Jensen not realizing Adderall is verboten.
Also, Junie Browning is firmly in my Brock Lesnar/Mike Bisping camp of "fighters I hope walk into a headkick, fall over, and shit their pants on TV".
