Jason Knight’s return to competition will have to wait.

The former UFC featherweight announced he will not be throwing bare-knuckle fisticuffs with Leonard Garcia next month in the main event of Bare Knuckle FC 7 after he sustained a rib injury in training.

According to Knight, the injury occurred several weeks ago. He attempted to push through, but ultimately was forced to pull the plug (via Twitter):
