A debris shield for engagement to a caster wheel is provided. The debris shield surrounds an opening in which a well of a caster wheel assembly is positioned. A flexible shield extending from the perimeter edge of the body and having a complimentary shape thereto, sweeps debris out of the path of the wheel rolling on a surface. Front and rear ends of the body are preferably pointed to provide angled portions of the debris shield of the flexible shield. Bristles of the shield may be reinforced by flexible adhesive and or mesh. An optional guard which is engageable to cover the shield around the projection points may be added.
