Saracens confirm Maro Itoje has fractured his jaw, but have not put a timeframe on how long the England and British & Irish Lions star will be out of action. A conservative estimate would be in the region of two months -- that's how long Anthony Watson was out for last year with his own broken jaw -- which would mean he'd be a doubt for the first couple of Six Nations rounds. England have plenty of depth at lock and blindside, but Itoje is regarded as one of the world's top players and not having him available would be a blow to Eddie Jones' side.
