If the Dallas Cowboys have a hole, they're going to plug it. ESPNDallas.com reports the Cowboys have come to terms on an agreement with linebacker Dan Connor, a former Carolina Panther and the sixth unrestricted free agent with whom the Cowboys have agreed to terms in the past two days.

Connor is an inside linebacker -- a Penn State alum like Cowboys linebacker Sean Lee -- who adds depth at a position where the Cowboys had none. Lee and Bruce Carter are the only two inside linebackers on the Cowboys' roster at this point, and Carter -- a second-round pick in 2011 -- is an unknown quantity. The team had talked about him as a possible 2012 starter, and he might yet be. But bringing in Connor gives the Cowboys some insurance in case Carter isn't ready and a reliable veteran who can play if Carter needs rest or more time to get up to speed. Connor is a strong player against the run in particular and should complement Lee's outstanding coverage ability.

More to come, too, in Dallas. The Cowboys have free-agent guard Nate Livings in for a visit Thursday, and it seems as though they're not letting many guys leave Valley Ranch without new deals.
