UPDATE -- Friday, March 3, 1:58 p.m. EST 

The UFC 209 co-main event pitting Khabib Nurmagomedov vs. Tony Ferguson for the interim UFC lightweight title is canceled. 

Nurmagomedov was transferred to Sunrise Hospital & Medical Center Thursday evening due to "weight management medical issues." At the hospital, Nurmagomedov was treated and has been discharged. 

On doctor's recommendation, however, Nurmagomedov has been pulled from Saturday's card. There is no word just yet regarding which matchup will replace Nurmagomedov vs. Ferguson on the main card.

FloCombat's Jim Edwards was on the scene, live broadcasting the drama. 

--Original report below--

UFC lightweight Khabib Nurmagomedov was reportedly hospitalized prior to the UFC 209 weigh-ins. He is scheduled to face Tony Ferguson for the interim UFC lightweight title tomorrow, Saturday, March 4, at Las Vegas' T-Mobile Arena.

The news was originally reported by Russian media outlet Izvestia, and a follow-up from ESPN.com's Brett Okamoto seemed confirm the report.

In the original news blast from Izvestia, Nurmagomedov's father commented, and Bloody Elbow provided a transcription.

"Yes, Khabib was taken to hospital," Abdulmanap said. "But it happened before weigh-ins by three hours so he may be okay."

Meanwhile, Ferguson successfully made weight for the bout, clocking in at 154.5.
