The Lions and Buccaneers have settled their differences on the George Johnson offer sheet, with Detroit agreeing to send the defensive end to Tampa Bay, league sources said. The Lions dropped their grievance after reaching an agreement with the Bucs. As part of the deal, the two teams will exchange unspecified late-round draft picks. The Bucs previously had signed the restricted free agent to an offer sheet of three years worth up to $9 million. But the Lions disputed the structure of the offer sheet, and the NFL assigned an independent arbitrator to look into the matter. But that now becomes a moot point. Johnson, 27, began his career in Tampa Bay until he was released in 2012. He spent the rest of 2012 and '13 with Minnesota before signing with Detroit last year.
