The Raiders added a fourth quarterback to the roster, trading a conditional 2019 seventh-round pick to the New York Jets for Christian Hackenberg.
Jets head coach Todd Bowles announced the transaction during a Tuesday meeting with local media.
Hackenberg joins a quarterback room that already contains starter Derek Carr and reserves EJ Manuel and Connor Cook.
Hackenberg was a second-round draft choice in 2016, but never played a regular-season NFL snap. He dressed for just five games.
He'll be competing for a roster spot in Oakland, as the Raiders will keep a maximum of three quarterbacks.
The Jets were clearly looking for new signal callers this offseason and got them, signing Teddy Bridgewater in free agency before drafting USC's Sam Darnold third overall in the NFL draft.
Hackenberg took a thinly veiled shot at the Jets Tuesday morning, questioning why a throwing motion overhauled by private coaches wasn't done earlier by the Jets. He was traded later that day
Hackenberg was taken two rounds before Cook in the 2016 draft – the Raiders traded up to get Cook in the fourth -- and both guys have failed to find footing on an NFL roster. Cook has been the No. 3 quarterback in two professional seasons, save an emergency playoff start in the 2016 season.
Manuel is older, though fared well in limited action last year.
Hackenberg has plenty of arm strength but has struggled with accuracy, and couldn't secure the Jets' starting spot that was most always up for grabs.
"I'm 23 and I got a lot of ball ahead of me," Hackenberg said Tuesday per the New York Daily News. "Hell, my career hasn't even started yet. So I'm excited about what the future holds."
News of the trade broke after Raiders head coach Jon Gruden's Tuesday media session, meaning he was not immediately available to comment on the transaction.
