Oregon coach Chip Kelly said Monday that he turned down an offer from the Tampa Bay Buccaneers because he has "unfinished business to complete" with the Ducks.

Kelly and the Bucs had been deep in the process of finishing a deal Sunday night.

The Bucs moved on from Kelly quickly, calling former Green Bay Packers and Texas A&M coach Mike Sherman back for a second interview, a league source confirmed to ESPN NFL Insider Adam Schefter.

The source said Sherman, who is also under consideration for Miami's offensive coordinator position, is the first candidate to be schedule for a second meeting.

The Tampa Bay Times also reported Sherman's second interview earlier Monday.

Kelly, who secretly interviewed with the Buccaneers last week, had been intrigued by the challenge of coaching at the highest level and not having to deal with parents and the NCAA oversights that are inherent to coaching in college, a source told ESPN's Joe Schad.
