The Cincinnati Bengals will bring in center Justin Hartwig and wide receiver/return specialist Dexter Jackson for visits this week, league sources said Monday.
Hartwig was released by the Pittsburgh Steelers on Sept. 4 after they were unable to pin down a trade partner.
Jackson spent the 2008 season with the Carolina Panthers, but he wasn't on an NFL roster last year.
Fullback Owen Schmitt also was scheduled to visit with the Bengals this week, but he signed with the Philadelphia Eagles on Monday night.
The Bengals lost to the New England Patriots38-24 in the season opener.
