Rugby-England wing May a Six Nations doubt

By Mitch Phillips LONDON, Jan 1 (Reuters) - England wing Jonny May requires surgery on a knee injury sustained playing for Gloucester last week and his participation in the Six Nations championship now looks doubtful. "Jonny has suffered a pretty significant knee injury that requires surgery," the club's head coach David Humphreys told the Gloucester Citizen. "He's seeing a specialist on Tuesday and based on the outcome of that we will have a much clearer picture of what needs to be done." May, one of the fastest players in the game, became a regular under Stuart Lancaster and started all of England's World Cup games. He was likely to retain his berth under new coach Eddie Jones but now faces a long spell on the sidelines after sustaining the injury during Gloucester's 39-39 draw with Harlequins at Twickenham on Dec. 27. England start their Six Nations campaign away to Scotland on Feb. 6 and visit Italy the following weekend. (Editing by Amlan Chakraborty)
