Panthers free agent guard/center Geoff Hangartner is scheduled to visit Buffalo on Friday.
Hangertner has a good market as both a center and guard but Panthers offensive tackle Jordan Gross has been pushing to keep his buddy in Carolina.
But Buffalo, which cut guard Derrick Dockery on Thursday, will get first crack.
