A staple cartridge is provided for retaining fully formed staples not clenched through body tissue. The staple cartridge generally includes staple pockets containing surgical staples having a backspan and first and second legs projecting from the backspan and staple pushers positioned within the staple pockets beneath the surgical staples. The staple pushers include body portions having first and second flexible fingers extending from the body portions and removably engagable with the backspan of the surgical staples. The flexible fingers include flexible stems extending from the body portions and head portions extending from the flexible stems. Each head portion includes a rounded distal tip positioned offset from and outward of a central axis of the stem and an inwardly projecting grasping portion for engaging the backspan of the surgical staple. Distal ends of sidewalls of the staple pockets are flared outwardly to accommodate movement of the head portions of the flexible fingers.
