He's still having the ICD to restart his heart fitted. There was talk of him playing on with the ICD, as there is a guy in Belgium called Anthony Van Loo who plays with one. He basically has a heart attack and falls to the floor, then the device kicks in and he gets back up again and carries on playing.

A bit too morbid for me, though.
