The Englishman had enjoyed a steady climb up the UFC's heavyweight rankings, with March's impressive win via armbar over Russian behemoth Alexander Volkov earning him a shot at fourth-ranked Blaydes.
The duo squared off in front of a boisterous 17 000-strong partisan crown at the O2 Arean in London last month. Unfortunately for all concerned, the bout was over after just 15 seconds as Aspinall tumbled backwards grabbing his knee, handing Blaydes a TKO victory.
On Wednesday, Aspinall took to Instagram to reveal he's going under the knife to repair his knee.
"Today is surgery day," the 29-year-old told his fans.
"I'm in London right now and I'm absolutely starving because I can't eat before surgery. I have suffered a torn MCL, a torn meniscus and some ACL damage, so going to get that fixed today."
