Promising cricketers that disappeared off the scene

[Sher Khan]

One that always comes to my mind is Adrian Barath, the 19 year old opening batsman that scored a magnificent hundred in an attempt to save a test in Australia vs the mighty Australians at the time. He looked like the real deal at the time, but seems to have not played any professional cricket for the last few years.

What are some other cricketers that disappeared of the scene?
