The Oakland Raiders remained busy during Saturday’s roster cut day. After trading their star defensive end, Jon Gruden and the Raiders added backup quarterback AJ McCarron, according to NFL Media’s Ian Rapoport.

McCarron signed with the Buffalo Bills in the offseason with a chance to earn the starting job but quickly became on the roster bubble after falling behind rookie Josh Allen and Nathan Peterman.

McCarron backed up Andy Dalton for four years in Cincinnati where he made three career starts, throwing six touchdowns and two interceptions. During this preseason he completed threw for 440 yards, no touchdowns and two interceptions while completing 40 of 66 passes.

The Raiders were looking for a backup quarterback after both EJ Manuel and Connor Cook looked inconsistent for much of the preseason.
