With Clint Boling rehabbing from a torn ACL, the Bengals may still look to add at least one quality lineman in free agency who's capable of opening the season as a starter if Boling isn't ready.
They've already signed Marshall Newhouse, but he's played mostly offensive tackle with the Packers, so Cincinnati may want another 'pure' guard on their roster to at least be a body in training camp.
Now, he is scheduled to visit with the Tennessee Titans:
Nwaneri finished the 2013 season with a respectable -0.3 grade by PFF, which ranked him as the No. 27 guard out of 60 eligible players who played in at least 50% of their team's snaps. A former fifth-round pick from the 2007 NFL draft, he has started 92 career games and played 104, including all but one in the past six years.
It's probably safe to say the Bengals have either moved on from him, or won't look to sign him until after the NFL Draft in the event they aren't able to draft a guard they like.
