The club mistakenly announced his signing on social media last week and quickly removed the post.
Henn joins fellow imports Alain Louis and Buay Tuach in a new-look Nuggets lineup that includes Ethan Rusbatch, Isaac Miller-Jose and Nuggets stalwart Matthew Bardsley.
Nuggets coach Jeff Sparrow described Henn, who has had professional stints in Mexico, Indonesia and Japan, as an extremely versatile player.
"He can put it on the floor, he can shoot it, he can pass it, he can drive it," Sparrow said.
"He just does a little bit of everything offensively.
"I can see games where he has six to 10 assists. I can see games where he has five to eight threes and 20 points."
Sparrow said "it’s hard to see where it’s going to shake out" when asked about Henn’s specific role in the side.
Rusbatch and Tuach shape as the main target men on the outside, while Louis, a point guard, plays a bit like a small forward and likes to drive to the hoop.
Henn’s main role will likely be to dominate the paint, but Sparrow has promised the Nuggets will operate a dynamic defensive system that requires versatile players like Henn.
