There's been concern over Jet Li's health, after a photo of the Chinese superstar looking "frail" went viral online over the weekend.

But Li's manager, Steven Chasman, brushed off these speculations this Tuesday, telling USA Today that the actor's "completely fine."

"We appreciate everyone's concern," Chasman was quoted to have said. "There's nothing wrong with him. There's no life-threatening illness. He's in great shape."

He also added: "If you took a picture of me at the wrong angle and wrong time of the day, I could look frail as well."

The much-talked about photo of Li was taken in Tibet, and it showed the 55-year-old appearing well past his age. It prompted news outlets to document the reaction from fans, with the South China Morning Post asking: "Is this the same Jet Li we all know?"

The report cited Li's battle with hyperthyroidism -- a serious thyroid disorder -- and past injuries from stunts as the reason behind his "shocking" look.

Li, best known for his roles in "Romeo Must Die" and "Lethal Weapon 4," last appeared in a Hollywood flick in 2014's "The Expendables 3." He was cast in the upcoming Disney live-action adaptation of "Mulan," scheduled for 2020.

Back in December, Li looked healthy in a video he posted for his website of him greeting his fans a happy new year.
