Business moves forward for top Ultimate Fighting Championship heavyweights, even as Jon Jones casts a shadow over the division.

Tom Aspinall will defend his interim heavyweight crown when he rematches Curtis Blaydes in the UFC 304 co-main event on Saturday at Co-op Live in Manchester, England. The first meeting between the two men was cut short in July 2022, as Aspinall suffered a serious knee injury just 15 seconds into the first round. He enters his second encounter with Blaydes on the strength of back-to-back routs of Marcin Tybura and Sergei Pavlovich. Aspinall has never fought beyond the second round in 17 bouts as a pro. Blaydes, meanwhile, has won four of his past five fights. The Elevation Fight Team export last suited up on March 9, when he wrecked Jailton Almeida with punches in the second round of their UFC 299 pairing.

As Aspinall and Blaydes approach their high-stakes duel, a look at some of the numbers that have accompanied them to this point:

31: Years of age for Aspinall, who was born on April 11, 1993 in Salford, England—some 200 miles northwest of London.

3: Aspinall victories by submission, accounting for 21% of his career total (14). His methods of choice: one heel hook, one straight armbar and one rear-naked choke. Aspinall holds 11 other victories by knockout or technical knockout (79%).

37: Significant strikes landed by Aspinall before he tapped former heavyweight champion Andrei Arlovski with a second-round rear-naked choke at UFC Fight Night 185 in February 2021. It established a high-water mark for the Team Kaobon rep that stands to this day.

9: Seconds needed for Aspinall to dispose of Satisch Jhamai with punches under the British Association of Mixed Martial Arts banner on March 28, 2015. More than nine years later, it remains his fastest finish to date.

33: Years of age for Blaydes, who was born in Naperville, Illinois, on Feb. 18, 1991. Whitney Houston’s “All the Man That I Need” was the No. 1 song on the Billboard Hot 100 list at the time.
