Raiders end brief tenure of Hackenberg

Quarterback Christian Hackenberg's brief tenure with the Oakland Raiders is already over. The Raiders on Tuesday waived Hackenberg, a move that came just three weeks after he was acquired from the New York Jets for a conditional seventh-round draft pick in 2019. The release of Hackenberg nixes the deal with the Jets and allows Oakland to retain the draft pick. The Raiders also waived linebacker Brady Sheldon to accommodate the signing of defensive tackles Ahtyba Rubin and Frostee Rucker. Hackenberg never entered a game in two seasons with the New York Jets after being a second-round pick in 2016. The trade came shortly after Hackenberg criticized New York's staff for what he perceived as a lack of coaching to correct his issues. Oakland has EJ Manuel and Connor Cook as the backup quarterbacks to starter Derek Carr.
