The Carolina Panthers continued to overhaul their offensive line on Friday, signing guard Milford Brown.

Terms were not disclosed.

Brown, 27, is the third offensive lineman signed by the Panthers during the off-season, joining guards Toniu Fonoti and Keydrick Vincent.

Brown appeared in 16 games - including 15 starts - for the St Louis Rams last season. The 330-pounder made nine starts at left guard, four at right tackle and two at right guard.

The 6ft 5in Brown has played in 47 games over parts of six seasons with the Rams, Arizona Cardinals and Houston Texans.
