This is not for the faint of heart.

On Tuesday afternoon, former UFC and WWE star Ronda Rousey shared a very graphic photo of the aftermath of her finger, following an accident on the set on the show 911.

This is by far the worst injury she has suffered, and this is coming from a woman who fought professionally in MMA and in the WWE.

“So the word is out I nearly lost my finger shooting 911onfox,” Rousey wrote on Instagram.

“Freak accident, first take of the day a boat door fell on my hand, I thought I just jammed my fingers so I finished the take before looking (I know it sounds crazy, but I’m used to live audiences and never showing pain unless I’m supposed to) after a break in the action I told our director the situation and was rushed via ambulance to the hospital where they promptly reattached my bone and tendon with a plate and screws.”

Despite the gruesome injury, Rousey stated she returned to filming the very next day.

“I returned to filming the next day and finished my scenes before returning home to recover. Modern medicine amazes me, I already had 50% range of motion back in 3 days.”
