Reggie McKenzie‘s exit will leave one of his lieutenants in his old role for the time being. The Raiders will promote Shaun Herock to the de facto GM role, Ian Rapoport of NFL.com tweets.

Herock, who followed McKenzie to Oakland from Green Bay in 2012, is expected to receive an interview for the full-time position, Rapoport adds. Herock previously served as the Raiders’ director of college scouting.

Although Herock was a McKenzie hire, Rapoport notes the 47-year-old executive is Jon Gruden‘s most trusted scout, at least among those he inherited from the McKenzie regime. While it would be a shock if the Raiders did go in-house to name McKenzie’s successor, they will use this arrangement for the time being. This may increase Herock’s chances of remaining with the organization after Gruden tabs the next front office boss.

“He’s a very talented personnel man; he has a lot of Raider history. We’re going to lean on him,” Mark Davis said, via Jerry McDonald of the San Jose Mercury News. “… I expect him to be a big part of this organization going forward, honestly.”

The Raiders may not hire a full-time GM — at least, the new exec may not have that job title — but they are planning to look for a new point person for their front office to work with Gruden. Lions exec Jimmy Raye, Jaguars player personnel director Chris Polian and former Buccaneers GM Mark Domenik — who worked with Gruden during his Tampa Bay tenure — are among names to monitor thus far. The Raiders may be looking for someone with experience and fortitude to push back against Gruden, Albert Breer of SI.com notes.

After spending 19 years in the Packers’ scouting department, finishing his Green Bay tenure as college scouting director, Herock relocated to the Bay Area after McKenzie took the Raiders’ GM job. He’s served in the same role with the Raiders for the past seven years. Herock’s father, Ken Herock, was a former Raider player and exec who worked with Davis during the process that led to McKenzie’s hiring.
