The Panthers are turning to a familiar figure to help fill their offensive line void following injuries to guards Chris Scott and Jeff Byers in Sunday's win against Atlanta. Veteran guard/center Geoff Hangartner is scheduled to fly to Charlotte on Tuesday to take a physical with the Panthers, a source close to Hangartner said Monday. If Hangartner passes the physical, he'll sign with the team. It would be Hangartner's third stint with the Panthers, who cut him during the first week of training camp. Hangartner, who has been living in Texas, started 12 games last season -- four at guard and eight at center. He was with the Panthers from 2005-2009 before playing at Buffalo for two seasons. After the Bills cut him before the 2011 season, Hangartner returned to Charlotte and started every game in 2011. The Panthers have been hard hit by injuries at guard. Rookie Edmund Kugbila went down with a knee injury in training camp, and opening-game starters Garry Williams and Amini Silatolu both have undergone season-ending knee surgeries.
