Marinelli, 59, talked with Bears coach Lovie Smith on Friday in anticipation of the defensive line coaching position opening up with the expected departure of Brick Haley to LSU.
The Bears, whose pass defense was ranked 30th in the league this season (21st overall), are in need of a defensive line makeover, and they have made an unspecified job offer to Marinelli, according to the Chicago Tribune.
But the Tribune and the Seattle Times reported that Marinelli was in Seattle on Monday to interview with the Seahawks, purportedly for the defensive coordinator's job, even though current coordinator John Marshall has not been dismissed yet.
The Seahawks were No. 30 in overall defense this season, and last in pass defense.
Seahawks president and general manager Tim Ruskell, who worked with Marinelli when both were with the Tampa Bay Buccaneers, also plans to meet with Buccaneers linebackers coach Casey Bradley, according to the Times.
Marinelli has never been a defensive coordinator at either the college or NFL level, though he made his reputation as a defensive line expert while with the Buccaneers. Bradley has been the Buccaneers' linebackers coach the past two years.
