A plate is mounted to a basketball backboard by bolts passing through the four standard bolt holes and forms a horizontal fulcrum. A standard hoop having a conventional L-shaped mounting bracket is positioned with the vertical leg thereof abutting the plate. A bolt passes from the plate through a hole in the vertical leg. A resilient shock absorbing mass is mounted between the outer face of the vertical leg and the end of the bolt, and acts as a shock absorbing device when the goal hoop is deflected about the fulcrum due to downwardly directed forces applied to the hoop. The shock absorbing device is positioned centrally with respect to the four mounting holes with all parts thereof ahead of the front face of the backboard.
