Bob Quinn and the Lions got their guy.
According to multiple reports, Amendola plans on signing with the Lions and reuniting with Matt Patricia.
His four-year deal with Oakland is for $66 million, with $36.75 million guaranteed, ESPN reported.
The fourth-round pick of the Patriots in 2015 has had 21 sacks over the past three seasons, including 7.5 a year ago.
Amendola, who started more than eight games for the first time in his career last season, has played 16 games in a season just twice (2010, '14).
Quinn made it clear heading into the offseason that Detroit needed more playmakers on defense.
The Lions signed Amendola to a $5.75 million, one-year contract, taking advantage of his comfort level with men he knew from New England. He reeled in a big one Monday.
The Lions either signed or agreed to a deal with several big-name veterans including wide receiver Danny Amendola, pass rusher Trey Flowers, cornerback Justin Coleman and tight end Jesse James.
The Detroit Lions continue to build Patriots Midwest.
Deals can not become official until the start of the new league year, at 4 p.m. ET on Wednesday.
Injuries have limited Rowe in recent seasons, but there's a history with Patricia, and Rowe (6-1, 205) has the size and skill set to play both inside and outside.
