What happened: Luis Hernandez weighed in seven pounds heavier than Sedriques Dumas for their short-notice light heavyweight fight at UFC Vegas 121. The newcomer hit the scale at 204 pounds ahead of the contest.

Why it matters: The weight disparity underscores the compressed preparation for Hernandez, who is making a remarkably fast turnaround following his second-round submission victory. Stepping up to face an established opponent on less than two weeks of notice creates a unique physical dynamic for his promotional debut.

What to watch: The light heavyweight matchup proceeds as scheduled on the UFC Vegas 121 main card.
