• The fighter shattered bones in his leg at UFC 261 when his opponent checked a kick after 17 seconds.
• He said a cut on his calf was where a bone pierced his muscle and skin.

UFC middleweight Chris Weidman shared an injury update on Instagram on Wednesday and showed a cut on his calf where he said his shin bone pierced through muscle and skin.

Weidman suffered the injury in devastating fashion 17 seconds into his 185-pound bout against Uriah Hall at UFC 261 on Saturday.

His opponent hadn't even thrown a shot or attempted a single takedown to get the win. He just checked a low kick from Weidman.

However, when he did, Weidman's leg wrapped around his shin, shattering his bones.

Weidman's ankle could be seen hanging from his calf. As he stepped back on the canvas, his leg buckled under the pressure.

Medics stormed the Octagon to assist Weidman, who was stretchered out of the VyStar Veterans Memorial Arena and rushed to a hospital.

He had surgery the following day and has been posting updates since.

"They put a titanium rod through the tibia. So, like, through the knee - they go through the knee and they put the rod in. They drill it through the tibia and make it straight and hard," he said in a video on Monday.

He's posted X-rays showing how clean the bone break was, said he did not expect to walk unassisted for eight weeks, and added that he would likely not train properly for six to 12 months.

He said on Instagram on Wednesday: "The cut on the back of the calf is from when I stepped down in octagon, and bone went through calf muscle and skin."

His wife, Marivi Weidman, said on Instagram on Sunday that the incident was "horrible" and that "freak things happen in life."

"My heart breaks for my husband because I know the work and dedication that he puts into his training everyday and the great man that he is, so I only want the best for him," she said.

"While this absolutely sucks in the moment and for some weeks to come, we are completely overwhelmed by the love and support we have far and wide and are very aware how blessed we are.

"All of that overpowers the awfulness of this situation."
