Plaintiff appeals an adverse Final Judgment in a slip and fall negligence action. We reverse because the trial court permitted the surprise admission of a highly prejudicial incident report over plaintiffs objection. See Binger v. King Pest Control, 401 So.2d 1310 (Fla. 1981) (trial court’s discretion must not be exercised blindly). Plaintiff requested production of the report during discovery. Defendant claimed it was privileged work product and did not list it on the joint pre-trial stipulation.

The substance of the incident report was that plaintiff stated she tripped over her own two feet at the time she fell. Plaintiff was surprised in fact at trial, and the resulting prejudice in the context of this slip and fall action is self-evident. We thus reverse for a new trial. See Binger, 401 So.2d at 1314 (pre-trial order should be modified if trial court cannot conclude that use of undisclosed evidence will not substantially endanger the fairness of the proceeding).

REVERSED.
