President Dana White informed Ludwig that he was being given the official fastest knockout time. Two days later, Keith Kizer and the Nevada State Athletic Commission denied that Ludwig would be given the record, with Kizer stating: "There's no legal avenue to overturn it" before going on to say "I timed it myself with a stopwatch. It was eight seconds. Officially, it's got to stay at 11 seconds, but unofficially, it could be at eight." Two days later, Dana White, along with his production crew posted a video to YouTube showing the times of UFC fights that hold the "Fastest Knockout" tag. Ludwig's knockout was timed at 6.06 seconds, compared to Chan Sung Jung's knockout at 6.26 seconds and Todd Duffee's knockout at 7.56 seconds. In 2019, Jorge Masvidal beat Ludwig's time with a knockout in five seconds.

Ludwig scored with strikes, including multiple grazing headkicks in the first round until Osipczak landed a combination, buckling the veteran.

The third round saw Ludwig land a big left early on and basically stalk Osipczak the rest of the round, scoring but failing to finish as Osipczak was seemingly out on his feet, walking away from exchanges and covering up. The bout was Ludwig's first since an eight-month recovery from a severe leg injury. Ludwig won by split decision.
