Television producer Peter M. Lenkov confirmed the news on his official Instagram account … posting a picture with Wily from behind the scenes of a television show and telling his followers he’s “heartbroken.”.

Lenkov says he’ll provide more details in the days to come … but is far too emotional now to discuss his longtime friend’s death.

TW — born Teila Tuli — started out as a sumo wrestler in the late 1980s — becoming a rare example of an American joining the prestigious Japanese sport and reportedly compiling a 57-27-14 record over the next two years.

Wily also fought in a different arena … slugging it out in one bout in the then-new UFC 1 — and, he’s the first fighter to ever lose a UFC brawl.

Taylor didn’t actually start acting until the mid-2000s … when he landed his breakout as Kemo in the Jason Segel movie “Forgetting Sarah Marshall.”

Two years later, he got his part as criminal informant Kamekona Tupuola on ‘Five-0’ a role he played in 171 episodes. He reprised the role in the shows “Macgyver” and “Magnum P.I.”
