What happened: The Duel Arena main-event finish came at 2:38 of Round 1. Jenkins said Nick Diaz, Tyron Woodley and Anthony Pettis had also received calls before he was selected.
Why it matters: The win followed Jenkins' split-decision victory over Chris Avila at MVP MMA 1 in May. Jenkins has voiced interest in facing Nate Diaz next.
By the numbers: 2 days: Jenkins' notice before replacing Dillon Danis. 2:38: Round 1 time of the technical-knockout stoppage.
What to watch: Whether a Nate Diaz fight develops is the next question after Jenkins' second appearance of the year.
