Royal Challengers Bangalore suffered a major blow hours ahead of their match against Gujarat Lions later tonight when AB de Villiers was ruled out with an injury.Disappointed to be missing the match tonight for RCB, due to injury. Good luck to @imVkohli and the team. Lets go @RCBTweets !!- AB de Villiers (@ABdeVilliers17) April 18, 2017De Villiers, who had hurt his back before the start of the IPL, had to miss the first two matches, before returning to slam a stunning 89 not out against Kings XI Punjab, albeit in a losing cause. He also looked dangerous against Mumbai Indians and Rising Pune Supergiant, making 19 and 29 respectively.(After two weeks of frenetic action, Sourav Ganguly, Michael Clarke pick their XIs for India Today)The South African superstar is one of RCB’s most successful batsmen of all time and peaked last year, smashing 687 runs in 16 matches.

This is a great opportunity for Gayle to become the first man to bring up 10,000 runs in T20 cricket – the West Indian powerhouse is currently three short.
