The Raiders will reportedly add experience and competition to their quarterback group.
Former first-round pick E.J. Manuel will likely sign with the Silver and Black, ESPN reported on Thursday afternoon.
Buffalo selected Manuel with the No. 16 overall pick in 2013 and he started 10 games as a rookie, but eventually lost a starting gig that now belongs to Tyrod Taylor.
He'll provide competition for the No. 2 spot behind unquestioned starter Derek Carr. That spot belonged to Matt McGloin, but he'll leave as an unrestricted free agent.
It was expected to fall to 2016 fourth-round pick Connor Cook and still likely will, but Manuel has started 17 NFL games and could provide experience to the position group. The Raiders kept three quarterbacks last season, but employed only two the year before.
It should give Cook a competitive push at the very least.
Manuel is familiar with Raiders offensive coordinator Todd Downing, who was Buffalo Bills quarterbacks coach in 2014.
