It seems it wouldn’t be a UFC without a high-profile withdrawal, and sadly, tonight’s UFC Fight Night 56 is no exception.

This one comes just hours before fight time, as Ian McCall, who made weight yesterday without issue, but is now reporting a blood infection which will prevent him from competing.

Via text messages with Ariel Helwani of MMA Fighting, McCall elaborates:

“Bacterial infection in my blood. My body just failed me after the weigh-ins… UFC blood tested me a few weeks ago and it showed I had a slight infection. I just figured I’d work through it. I’m in such great shape and am so healthy I didn’t think it would affect me like this. Since getting to Brazil, I’ve had a fever and only slept one to hours a night.”

McCall was reportedly rushed to the hospital last night and is currently on antibiotics. He offered his apologies to the UFC, and particularly, his opponent John Lineker:

“We both needed this fight for so many reasons. We still do. Hopefully the UFC grants me another opportunity.”
