The Monday after UFC 223 turned into a big day for two fighters that could have been part of it.

Former UFC middleweight champion Chris Weidman was never connected to this past Saturday’s card in Brooklyn, but being a native New Yorker, he likely would have been in consideration if it wasn’t for a thumb injury.

Weidman went under the knife Monday morning for a second time in hopes of having the injury fixed for good and continuing his career.

“Having a second surgery on my hand today,” he posted on Twitter. “I appreciate the support of all my fans and I’ll be back in the Octagon in no time. The comeback is always greater than the setback!”

Meanwhile, Tony Ferguson was slated to main event the UFC 223 event vs. Khabib Nurmagomedov before suffering a serious knee injury while at a media event for the promotion.

Ferguson, like Weidman, is set to be sidelines for several months after surgery.

“Good morning,” he posted online. “Carpe Diem…(seize) The Carp!!! Up Early, No Coffee, Bout To Head In For Open Knee Surgery…As You Can Tell (I’m) Ecstatic.”
