It'll hype up the eventual Izzy/DDP fight even more then it already is, I mean they MIGHT even be able to get settle it on the first UFC Africa card in early 2024 if the stars align perfectly.
Both will also have full camps and be closer to a 100% going into that instead of one of them being compromised, the UFC expecting the Whittaker/DDP winner to be able to make that quick of a turnaround was pretty unrealistic to being with so this isn't really surprising.
Izzy/Strickland will get some attention, but the matchup itself isn't that interesting.
Strickland's style is tailor made for Izzy, he doesn't have a lot paths to victory here and will get pieced up or outpointed. Even if Strickland plays it safe, he won't be able to outpoint Izzy.
