Musgrave won’t return to Raiders

The Oakland Raiders are making changes on their coaching staff after their first playoff berth in 14 years.

A person familiar with the plans said Tuesday that quarterbacks coach Todd Downing will replace offensive coordinator Bill Musgrave next season on coach Jack Del Rio’s staff.

Musgrave’s contract was up and will not be renewed by the Raiders in the first changes to Del Rio’s staff since he was hired in 2015.

Oakland (12-5) made the playoffs and posted a winning record for the first time since 2002 before quarterback Derek Carr broke his leg in the second-to-last game of the regular season.

Musgrave helped develop one of the NFL’s top offenses in his two seasons in Oakland as Carr grew from an upand-down rookie season before Musgrave arrived into a possible MVP candidate this season.

Carr threw for 3,937 yards and 28 touchdowns this season.

The Raiders ranked sixth in total offense, seventh in scoring and 10th in yards per play this season.

But Oakland stumbled in the season finale with backup quarterback Matt McGloin and then lost the playoff game behind rookie Connor Cook.

Del Rio publicly criticized Musgrave’s playcalling at times during the season, wondering why Latavius Murray didn’t get more carries in a season-ending loss at Denver that cost the team a division title and first-round bye.

49ers continue interviews: The San Francisco 49ers interviewed Carolina defensive coordinator Sean McDermott for their head coaching vacancy and ESPN analyst Louis Riddick for their general manager job.

McDermott became the first defensive coach to interview with CEO Jed York for the coach opening.

Riddick, a ninthround pick by San Francisco in 1991, played six seasons in the NFL with Atlanta, Cleveland and Oakland. He then spent time in the front office in Washington and Philadelphia after his playing career, first as a scout and then director of pro personnel with both teams before becoming a TV analyst in 2013.
