Panthers free agent offensive lineman Geoff Schwartz is scheduled to visit the San Francisco 49ers this week after he meets with the Minnesota Vikings on Monday, according to a league source with knowledge of the situation. Schwartz grew up in California as a 49ers fan. Schwartz, 25, is also being pursued by the Detroit Lions. Schwartz became an unrestricted free agent when the Panthers didn't give him a restricted free agent tender offer. The 6-foot-6, 331-pounder from the University of Oregon is a former Panthers seventh-round draft pick who started every game two seasons ago. Source: Scout.com
