The Raiders agreed to a deal with former Titans quarterback Marcus Mariota on Monday, according to the NFL Network's Ian Rapoport.
The terms of Mariota's deal have not been disclosed. He is expected to serve as the backup for Derek Carr, who has been the Raiders' starter since 2014.
"Marcus Mariota is nearing a deal with the Oakland Raiders to come in and back up Derek Carr," Rapoport said on Monday. "[Raiders general manager] Mike Mayock was a huge fan of Mariota in the pre-draft process [in 2015]. ...Not a big surprise he has targeted Mariota to come in and backup Derek Carr.
