Defensive coordinator Kane Wommack will serve as South Alabama's interim football coach until a new head coach is hired, a source confirmed to AL.com on Sunday.

Former head coach Joey Jones announced his resignation Nov. 20, effective at the end of the season. The Jaguars finished the year Saturday with a 22-17 loss at New Mexico State, dropping them to 4-8 in Jones' final season.

The 30-year-old Wommack has been South Alabama's defensive coordinator the last two seasons. Prior to joining the USA staff, he was defensive coordinator at Eastern Illinois for two seasons.

Wommack has also coached at Ole Miss, Jacksonville State and Tennessee-Martin. He played fullback at Arkansas and Southern Miss.

South Alabama athletics director Joel Erdmann is expected to begin interviewing head-coaching candidates this week, with the goal of having a hire made before the beginning of the early signing period Dec. 20.
