The lightweight division remains among the deepest in the sport, and Saint Denis must clear multiple ranked contenders before a title shot materializes. A win over Pimblett would strengthen his standing, but the division's queue includes fighters angling for champion Ilia Topuria, whom Pimblett has publicly targeted. Pimblett has downplayed a Topuria matchup as his next step, noting his record and the obstacle Saint Denis presents first. With only one scheduled bout before year-end, the path for Benoît Saint Denis to become UFC Lightweight Champion on December 31, 2026 would require a victory Saturday plus a subsequent title fight booked and won within roughly five months — a compressed timeline in the current standings.
