The Titans continue to look for ways to upgrade their offensive line:

Wells was a 7th round pick of the Green Bay Packers back in 2004. He was their starting center from 2005-2011 before moving on to the St. Louis Rams in 2012 where he has been for the last 3 seasons.
The Titans drafted a center, Andy Galik out of Boston College, in the 6th round. Bringing in Wells for a visit and drafting Galik in the 6th round doesn't mean that the Titans are giving up on Brian Schwenke, but it isn't exactly a ringing endorsement.
