Matt Grice, a UFC featherweight and full-time Oklahoma City police officer, underwent brain surgery late Sunday and is in critical condition after the car he was in was hit from behind while he was stopped at a red light.
According to News9.com, the accident occurred near Shawnee, Okla. Grice underwent surgery at the Oklahoma University Medical Center, according to the News9 report.
NewsOK.com reported that Grice was not wearing a seat belt when he was struck from behind by a van driven by Michael Monroe, 53, of Oklahoma City. Monroe told police he was distracted by someone in his van, causing him to hit the rear of Grice's Jeep.
The force of that collision sent Grice into a Jeep driven by Christopher Sparks, 23, of Seward, Okla. Sparks was not injured.
Grice, 32, is one of the greatest wrestlers in Oklahoma high school history. He won four consecutive state titles and was Outstanding Wrestler three times. He attended the University of Oklahoma, where he earned a degree in sociology.
He is 15-5 in his MMA career, including a 2-5 mark in the UFC.
Prayers go out to Grice, his wife and two daughters for his full and complete recovery.
