According to The Cincinnati enquirer's Joe Reedy, the Bengals have officially announced visits from four players. Three of the players, Terrence Newman, BenJarvus Green-Ellis and Joel Dreessen, we knew about, but there was a fourth player that we were unaware of: defensive end Derrick Harvey.

Harvey is a former first-round pick from the 2008 NFL draft for the Jacksonville Jaguars. He played three years in Jacksonville before he was waived in July of 2011. He signed with the Broncos for the 2011 season, but only played in five games.
In his career he has made 92 tackles and made only eight sacks, which is extremely low production for a No. 8 overall pick. He is likely who the Bengals are hoping could replace Jonathan Fanene and Frostee Rucker at defensive end in the rotation to keep some depth on the defensive line.
Note that Michael Bush was not on the list. That is because the team's meeting with Bush has not yet concluded and they will officially announce his visit when he leaves. For now, he is scheduled to meet with the Seahawks and the Bears.
