The Las Vegas Raiders fired defensive coordinator Paul Guenther following Sunday’s 44-27 home loss to the Indianapolis Colts.

Defensive line coach Rod Marinelli will be the interim defensive coordinator for the remainder of the season, according to the Raiders.

Guenther, 49, was dismissed after the Raiders allowed more than 40 points for the second time in three games. Las Vegas (7-6) has given up over 40 on three occasions this season.

Entering the game, the Raiders ranked 28th in scoring defense (28.9 points per game) and 22nd in total defense (378.2 yards per game).

Las Vegas gave up 456 yards in the loss to the Colts — 244 passing and 212 rushing. Colts rookie Jonathan Taylor rushed for a season-best 150 yards and two touchdowns.

Guenther was in his third season as the Raiders’ defensive coordinator.

Marinelli, 71, is in his first season with the Raiders after spending the previous six seasons as defensive coordinator of the Dallas Cowboys.

Marinelli also served as defensive coordinator of the Chicago Bears from 2010-12 and was head coach of the Detroit Lions from 2006-08. He had a 10-38 record with the Lions, including the infamous 0-16 mark in 2008.

The Raiders will host the Los Angeles Chargers on Thursday.
