Dan Mullen is out as Florida's football coach, sources told ESPN on Sunday.
Greg Knox will fill in as interim coach.
A staff meeting was called for 1 p.m. ET and a team meeting for 1:30. The Gators have lost five straight games to Power 5 opponents and are 5-9 against Power 5 teams dating back to last season.
Mullen, in his fourth season at Florida, had the Gators in the SEC championship game last season, but they need to beat Florida State on Saturday to avoid a losing season.
