Rosen, the Cardinals’ first-round pick in 2018, will be back in the NFC West in 2021. He will return to the 49ers.
The 49ers signed him off the practice squad of the Tampa Bay Buccaneers for the final two weeks of the year when C.J. Beathard was the only healthy quarterback they had.
Since being drafted No. 10 overall, Rosen has now been with the Cardinals, Miami Dolphins, Buccaneers and now the 49ers.
The 49ers also re-signed running back Austin Walter, who returned kicks before landing on injured reserve.
