Union County football coach Ronny Pruitt has "retired/resigned" from the school, with defensive coordinator Kepa Sarduy assuming the post.

One of Northeast Florida's longest-tenured football coaches has left his post only days before the season's start.

Longtime football coach and athletic director Ronny Pruitt has stepped down from Union County, with defensive coordinator Kepa Sarduy assuming both roles. Sarduy's appointment was first reported by the Gainesville Sun.

In a Thursday night tweet, the Union County athletic program said, "Today our HC Ronny Pruitt has decided to retire/resign from his position at Union County. We are greatly appreciative of everything that he has done for our school, program & community. DC Kepa Sarduy has been promoted as the new head coach and athletic director of UCHS!"

The news comes only one day before Union County's scheduled preseason football classic against Crescent City. The team opens its regular season Aug. 23 against Lanier County of Georgia.

Pruitt has compiled a record of 72-28 in 10 seasons with the Fightin' Tigers, and he is 97-46 in 14 years of coaching overall in Florida and Georgia.

He also coached for a single season in 2006 at University Christian, where his older brother, Robby Pruitt, had led the team to Florida High School Athletic Association championships in 1987, 1989, 1991 and 1992. Pruitt overcame a life-threatening bout with flu complications in 2016.

In addition to his previous role as defensive coordinator, new coach and athletic director Sarduy served as head coach of the Fightin' Tigers' boys weightlifting program.

He had coached Newberry from 2013 to 2015, with a record of 15-14.
