The Bengals were in attendance with several other teams at the University of Auburn's Pro Day, according to WVTM's Kyle Burger.
The Bengals, like most of the other teams, were likely paying attention to running back Onterio McCalebb, who impressed teams at the Combine by running a 4.34 in the 40-yard dash. The Bengals are looking for more speed at the running back position to add a home run threat opposite BenJarvus Green-Ellis.
McCaleb impressed at Auburn's pro day, running an unofficial time of 4.29, making him one of the fastest players in this year's draft class. However, some may have concerns about his size as he stands at 5-foot-10 and only weighs 164 pounds.
Defensive end Corey Lemonier, who could also interest the Bengals as both Michael Johnson and Carlos Dunlap are going to hit free agency following the 2013 season, decided not to run the 40-yard dash because he already impressed at the combine with a time of 4.60.
The non-combine invites included 6-foot-3 wide receiver Emory Blake, who ran a 4.62 at the school's pro day. If you're wondering, he's the son of former Benglas quarterback Jeff Blake, who was in attendance and threw passes to him. Guard John Sullen was also in attendance, but struggled, putting up only three reps on the bench press.
This is just one of dozens of pro days that the Bengals will attend leading up to the 2013 NFL draft. For the full schedule, go here.
