A surgical stapling instrument has upper and lower elongate jaws for receiving a staple cartridge and an anvil respectively. A pusher bar and knife assembly including a pair of pusher bars and a central knife carrier moves longitudinally relative to the jaws to eject staples sequentially from the magazine and to form laterally spaced staple rows in tissue gripped between the jaws while the knife cuts the tissue along a line between the staple rows. The instrument includes structure for locally supporting the jaws in the region of the pusher bar cams and knife blade as these elements move along the jaws to resist forces created during staple ejection and shaping which tend to vertically separate and/or laterally distort the jaws.
