Cape Town: Jos Buttler could be in hot water after a video of the England wicketkeeper's foul-mouthed rant at South African pacer Vernon Philander went viral on social media with former batsman Kevin Pietersen urging people to leave Buttler alone.

England registered a thrilling 189-run win over South Africa in the second Test match to level the four-match series 1-1 at Newlands here on Tuesday. During South Africa's second innings when the hosts were playing for a draw, the stump mic picked up Buttler launching an angry tirade at Philander after he appeared to get in the way of a throw to the stumper. Ben Stokes, who was stationed at first slip, also joined him, saying: "Don't stare him out. He's got a point, mate."
