Fox News in Tennessee reports that 51-year-old Beth Plant - mother of IBF super middleweight champion Caleb Plant - was shot and killed by a deputy in Cheatham County.

According to the Tennessee Bureau of Investigation, paramedics were transporting Beth Plant to the hospital early Saturday morning when she allegedly became combative and pulled a knife from her backpack.

The ambulance driver pulled over on New Hope Road and Highway 41A and called for police.

The TBI states in their reports that when the Cheatham County Sheriff's Office arrived, Beth Plan allegedly brandished the knife on a deputy - who shot her. She died from the sustained injuries at the hospital.

Caleb acknowledged the passing on social media Saturday, "Love you forever and always momma. You always told me “work hard bubba” and I did."

No details have been given regarding why Beth Plant was being treated by paramedics.

An investigation is ongoing.

Caleb Plant, who had a very rough upbringing, achieved his dream when he captured the IBF world title in January with a gutsy decision win over Jose Uzcategui, who went down twice in the contest.
