In particular, the staple cartridge includes a plurality of surgical staples in an annular array. The anvil includes an anvil member and a shaft extending therefrom. The anvil member defines a plurality of staple pockets for deforming the surgical staples. The anvil is movable relative to the staple cartridge component between spaced apart and approximated positions to adjustably clamp tissue between the staple cartridge and the anvil. The buttress member is concentrically aligned with the plurality of staple pockets defined in the anvil member. The buttress mount is detachably secured with the shaft of the anvil. The buttress mount includes at least one support member radially extending outward to secure the buttress member to the anvil member.
