In 1967 Snow jarred his back while bowling against India at Edgbaston. X-rays found that he had a sacroiliac joint abnormality which had become inflamed and that the only cure was traction and complete rest. As a result, Snow became very insistent that he not be overbowled and was frequently accused of "not trying" when he was too ill to field properly. Once Ted Dexter made him bowl throughout a session for Sussex and he took a week to recover. When not bowling Snow often lounged around the outfield – ignoring the game if he felt it wasn't going anywhere – but had a fine throwing arm when he wanted to use it.
