Ateman will step up as the Raiders' No. 4 wide receiver against the Packers on Sunday, Paul Gutierrez of ESPN.com reports.
Ateman is facing a notable opportunity with Tyrell Williams (foot), Zay Jones (coach's decision) and Dwayne Harris (ankle) all inactive. The big-bodied wideout is a candidate to see key looks in Oakland's aerial attack Sunday, though he may not have a consistent role once the team's other weapons get healthy.
