The 2025 boxing calendar closes with an intriguing super welterweight title clash as undefeated prospect Callum Simpson defends his British, Commonwealth, and European titles against veteran contender Troy Williamson. Simpson, riding a wave of knockout wins, enters as the heavy favorite in what could be a defining moment for his career. Williamson, with a history of upsetting odds in domestic bouts, aims to rebound from recent setbacks and capture the hardware on home soil. This 12-round main event, promoted by Boxxer Promotions, promises high drama in a packed arena, with Simpson’s power clashing against Williamson’s experience in a fight that could go the distance or end abruptly.
Venue Location
The fight will take place at the First Direct Arena in Leeds, Yorkshire, United Kingdom. This 13,781-seat multi-purpose venue, opened in 2013, has hosted numerous boxing events and is known for its electric atmosphere, modern facilities, and proximity to Simpson’s hometown, giving him a potential edge with local support.
The main event ring walks are expected around 5:00 PM GMT (12:00 PM ET / 9:00 AM PT), with the undercard starting earlier in the afternoon. The bout will be broadcast live on BBC Three in the UK and available for streaming on BBC iPlayer, with international options via Boxxer’s platforms.
Injury Report
No major injuries have been reported for either fighter leading into the bout. Callum Simpson, 28, enters fully healthy after a rigorous training camp focused on endurance for a potential distance fight. Troy Williamson, 31, has recovered from minor setbacks in previous camps and is cleared for action, though his history of durability issues (four losses, three by KO/TKO) could be a factor if the fight turns grueling. Both camps have emphasized full preparation, with no last-minute concerns noted.
Fighter Matchups
This super welterweight (154 lbs) bout pits Simpson’s aggressive, power-punching style against Williamson’s technical boxing and counterpunching. Simpson, a southpaw with explosive speed, favors mid-range exchanges and body work to wear down opponents, while Williamson relies on footwork, jabs, and volume to outpoint foes. Expect Simpson to press early for a KO, but Williamson’s experience could force a tactical chess match if he survives the initial rounds.
Key stylistic contrasts:
Power vs. Precision: Simpson’s 72% KO rate (13/18) could overwhelm Williamson, who has been stopped in 3 of his 4 losses.
Reach and Stance: Simpson’s orthodox stance vs. Williamson’s southpaw could lead to awkward clashes, favoring Simpson’s quicker hands.
Endurance: Williamson has gone the distance in 12 fights, while Simpson has only 3 decisions, suggesting a late-round fade risk for the champion if pushed.
Fighter Records
Callum Simpson: 18-0-0 (13 KOs), undefeated British prospect ranked in the top 10 at super welterweight by major sanctioning bodies.
Troy Williamson: 21-4-1 (15 KOs), former British champion with experience against top domestic talent but coming off mixed results.
Recent Team Forms
Simpson enters on a hot streak, having won his last five fights by KO/TKO since early 2025, including a dominant title defense against Zak Chelli in August. His form rating is 9/10, with improved footwork and power evident in recent bouts. Williamson has a 3-2 record in his last five, with wins over prospects but losses to elite competition like Josh Kelly in 2024. His form is 6/10, showing resilience but vulnerability to pressure fighters like Simpson.
Fight History
This is the first meeting between Simpson and Williamson, adding intrigue to the matchup. No prior head-to-head history exists, but both have competed in the British domestic scene, with Williamson’s experience against similar power punchers (e.g., loss to Ted Cheeseman in 2021) potentially informing his strategy. Simpson’s unblemished record means he’s yet to face a veteran like Williamson, making this a stylistic test for the rising star.
Betting Trends
Simpson has gone the distance in 5 of his last 10 fights, trending toward unders on rounds (6-4 under in last 10). His bouts average 8.2 rounds, favoring under 10.5. Williamson’s fights often end early (15 KOs in 21 wins), but he’s durable in losses, with 3 of 4 defeats by stoppage. Recent trends: Favorites in super welterweight title fights are 8-2 in the last 10 UK-based events, covering the spread 70% of the time. Unders have hit in 60% of recent British title bouts due to tactical boxing. League-wide (or boxing-wide) for December 2025, unders are at 55% in fights with undefeated favorites, reflecting cautious styles.
