Source: Bengals tried out Justin Hartwig, Eric Ghiaciuc, Dexter Jackson

The Cincinnati Bengals kicked the tires on a few veteran offensive lineman, auditioning offensive linemen Eric Ghiaciuc and Justin Hartwig, according to a league source with knowledge of the situation.

Ghiaciuc has previously played for the Bengals, New England Patriots, Cleveland Browns and the Kansas City Chiefs.

Hartwig was cut by the Pittsburgh Steelers this preseason as they chose to go with first-round pick Maurkice Pouncey as their new starting center.

The Bengals also tried out wide receivers Dexter Jackson, Eron Riley, London Crawford and Kole Heckendorf.

A former second-round draft pick from Appalachian State, Jackson has excellent speed. However, he has bounced around from the Tampa Bay Buccaneers and the Carolina Panthers.

Jackson hasn't been given consistent opportunities to play wide receiver in the NFL, but has upside and athleticism.

Riley was previously with the Baltimore and has a good size-speed combination, but was cut during the final major roster cutdown and wasn't signed to the practice squad.
