Raiders cut QB Hackenberg

The Oakland Raiders won’t be sending a 2019 draft pick to the New York Jets for Christian Hackenberg after all.

Oakland released Hackenberg from its 90-man roster Tuesday, three weeks after acquiring the backup quarterback from the Jets for a conditional seventh-round choice in 2019. A traded player typically must remain on his new team’s roster for a period of games or past mandatory roster reduction dates for conditional choices to change hands.

New Raiders coach Jon Gruden said the decision was made to cut Hackenberg because roster spots were needed to sign veteran defensive linemen Frostee Rucker and Ahtyba Rubin.

“I was disappointed in not really giving Christian the opportunity to go to camp,” Gruden said after practice Tuesday. “We felt like we needed to add a couple defensive linemen. We ran out of numbers, and that’s not good at that position heading into camp.”

The Raiders headed into their mandatory three-day minicamp Tuesday with Derek Carr, Connor Cook and EJ Manuel as their top three quarterbacks.
