After hosting one of the most entertaining cards of the year in May, UFC returns to O2 Arena in London this Saturday. The last event in London only had three of the 12 total fights on the card go the distance.
Aspinall, ranked No. 6 in ESPN's divisional rankings, is undefeated in the UFC with finishes in all five of his appearances in the Octagon. Andrei Arlovski is the only one of his opponents to make it past the first round with Aspinall, only to be finished in Round 2.
With an impressive win, either fighter could propel themselves right into contention for the heavyweight title.
Saturday's main card is on ESPN+, starting at 3 p.m. ET. The prelims are on ESPN+ at noon ET.

Ian Parker's betting tip for Curtis Blaydes vs. Tom Aspinall
Coming off the biggest win of his career, Aspinall will be looking to add another big name to his resume in Blaydes. If Aspinall can get this win, he will have a great shot at being the next in line for a title fight. For Aspinall, I think stylistically this is going to be a tough one for him as his cardio will be heavily tested by Blaydes. Aspinall has great striking and a great ground game, but has never -- in his whole career -- been outside of the second round, and against a grinder like Blaydes who has, that can be where he struggles. Look for Blaydes to go to his bread and butter with the wrestling and try to wear down Aspinall throughout the fight. At underdog odds, I am taking the more experienced Blaydes here.
