UConn football defensive coordinator Lou Spanos has taken a leave of absence for personal reasons, the school announced Thursday.

The school provided no further details and did not say whether Spanos is expected to return this season.

The 51-year-old served as UConn’s defensive coordinator from 2019-21 and became the Huskies' interim head coach after Randy Edsall left the team two games into a 1-11 season a year ago.
