Sehwag was dropped after a double ton.
Err no he wasn't. Sehwag's got a good run after his last test 100, which was a ton, not a double ton. After his 117 he had scores of 25, 30, 9, 23, 49, 0, 2, 19, 6. Also worth noting is that before his 117, his last ton was a whopping 31 innings ago. I would think its droppable form however you look at it.
In ODIs after is 219 against WI, his scores were 10, 20, 0, 30, 5, 96, 15, 3, 34, 4, 31. Hardly a great run.
Sehwag got his chances after he scored his last tonnes in both ODIs and Tests.
