Undefeated featherweight prospect Tommy McMillen (9-0, eight finishes) makes his Octagon debut against Manolo Zecchini (11-4), who returns from a nearly three-year layoff after shoulder surgery and a 3:51 UFC loss to Morgan Charriere in 2023. Both hit the scales cleanly at yesterday's weigh-ins—McMillen at 145.5 lbs, Zecchini at 145—with no withdrawals or issues reported. Trader consensus favors McMillen's grappling edge, height (6'0" vs. 5'8"), and same-reach advantage (74"), bolstered by his gritty DWCS majority decision over David Mgoyan despite striking defense lapses. Zecchini's knockout power (nine KOs) and stylistic striker matchup offer upset potential, but rust and defensive grappling concerns temper expectations in this UFC Vegas 115 main card opener.
