I've already done this three times, it's given me worries about making weight on one of my fighters once, and I accidentally did it a couple days ago. The only time I had trouble is with a fighter with natural weight 16 pounds over the weight class he was contracted to and with bad cardio. The third time hasn't hurt me yet, but the quick fight is tomorrow. Now I've received two contract offers for two fighters who currently have quick fights booked, set to be fought tomorrow IIRC, and if this is going to cause problems I'd want to refrain from signing off on these contracts until later. If I don't get offered a fight like 3 days from now there shouldn't be an issue, right? even though I don't want to turn down any fights.
Sorry for the huge paragraph..
