Weidman says despite the severity of the injury, doctors told him he'll be leaving the hospital TODAY -- and he's "excited to get back home."
36-year-old Weidman suffered the injury to his right leg while throwing a kick against Uriah Hall in the opening seconds of their UFC 261 fight in Jacksonville.
He was rushed to the hospital where doctors performed surgery to treat the injury -- which included using a metal rod to stabilize his tibia.
Weidman predicts his recovery will take 6 to 12 months -- and he's laser-focused on getting back in the Octagon to fight again ... clearly inspired by guys like NFL quarterback Alex Smith, who suffered a catastrophic leg injury only to return to the field after a tough rehab and recovery.
