Cut were quarterbacks Sam Keller and Jeff Otis, and defensive lineman Tranell Morant.

The three waived players freed up roster spots for draft picks Arman Shields and Trevor Scott, as well as “franchise” free agent Nnamdi Asomugha, who signed his contract tender.

Keller was recently signed, after participating in the Raiders’ rookie minicamp. Morant also won a contract as a tryout at the camp. Otis was with the Raiders in camp last season, waived, and re-signed this offseason.

It’s possible one of the three, likely a quarterback, could be re-signed once persona non grata running back LaMont Jordan’s fate is decided, freeing up a spot.

The Raiders have 80 players participating as camp opens, with Jordan in limbo and international practice squad player Mauricio Lopez taking part. (Lopez will be on the practice squad all year, does not count against the 8-player limit, and is ineligible to be called up.)

The cutdown to 75 players follows the third preseason game, with the cutdown to the final 53-man roster due between the final preseason game and Opening Day.
