West Virginia defensive coordinator Jordan Lesley is out and will be replaced by Jeff Koonz for the rest of the season, sources confirmed to ESPN.
Lesley had served as West Virginia's primary coordinator since 2021 and had been on coach Neal Brown's staff at WVU and Troy since 2016.
The Mountaineers are 45th nationally in points allowed and have allowed 99 points in their last three games.
Lesley was nominated for the Broyles Award, given to the nation's top assistant, in 2020 and 2021, and oversaw a defense that led the Big 12 in sacks and improved its pressure numbers last season.
