But the giant from the Netherlands has decided to hang up gloves after dealing with vertigo, hearing loss and other issues.
"I was contacted by the UFC last week for a fight," Struve said ... "However, I’ve decided it’s my time to retire from fighting."
"I’ve had an inner ear issue that I’ve been battling since May [of] last year. I caught a viral infection that has damaged my vestibular system and the hearing nerve in my right ear."
Struve says his doctors expected him to make a full recovery -- during his fight against Tai Tuivasa in October 2020, he got flush on his right ear, which made everything worse.
