Florida assistant Doc Holliday has interviewed with Marshall and is the top candidate to fill its head coaching vacancy, a source close to the search told The Florida Times-Union.
The safeties coach interviewed in West Virginia on Tuesday and was back at Florida practice Wednesday.
"I did go up there [Tuesday]," Holliday told the paper. "Any assistant coach at some point wants to be a head coach, but other than that I have no comment.
"Right now I haven't made any decisions. Other than that, I'm out here trying to get Florida better. That's all I'm concerned about right now."
Holliday previously served as an assistant at NC State from 2000-04 before joining Urban Meyer's staff this offseason.
Mark Snyder, defensive coordinator at Ohio State, is also a candidate, according to the Times-Union.
Bob Pruett retired this spring after the the Thundering Herd finished its final season in the Mid-American Conference with a 6-6 record, its first non-winning season in 21 years. The school moved to Division I-A in 1997, a year after it won the Division I-AA national championship.
Pruett is the most successful coach in Marshall history, going 94-23 five MAC championships and five postseason bowl victories.
