Michael Chiesa had to be taken to the hospital as the result of an injury suffered ahead of his UFC 223 fight against Anthony Pettis this weekend after Conor McGregor went wild at the Barclays Center in Brooklyn on Thursday.
McGregor attacked a bus during a confrontation with other fighters at media day, even going so far as to pick up a guard rail:

The injury is severe enough to keep him from entering the Octagon, per Ariel Helwani of MMAFighting.com:
Emil Grzelak posted (and has since deleted) footage from inside the bus during the incident. Warning: Video contains NSFW language.
The 30-year-old Chiesa was looking to bounce back after losing his last fight to Kevin Lee at UFC Fight Night in Oklahoma City back in January. That bout ended a three-match winning streak and dropped his record to 14-3-0.
This weekend was a chance for him to get back in the win column.
