Shaw landed heavily on the ground and appeared to be unconscious. The incident saw the defender leaving the pitch in an oxygen mask and a neck brace. Reports say he was immediately taken to a hospital.The game was Shaw's first England start in three years. After severely breaking his leg against PSV during the 2015/16 season, the defender was finally back on his feet and rediscovering his form.The 23-year-old recently opened up about the injury, revealing that he was incredibly close to losing his leg.Speaking of the injury, the defender said, "I nearly lost my leg, I was really close to actually losing my leg. I never knew that until six months later when the doctor told me.""At the time, they were thinking about flying me back [from Holland] and if I'd have flown back, I would probably have lost my leg because of the blood clots and stuff in the leg.”Following the Nations League game, an FA spokesperson revealed that Shaw was "fine and walking and talking in the dressing room" and will undergo further tests at Wembley.England also tweeted from their official account: "Luke is awake and alert, having been assessed by our doctor and given an X-ray."Fans were left gutted for the defender and took to Twitter to show support:That Shaw incident is horrendous. After what he's been through, I sincerely hope that he makes a speedy recovery and returns to the field as soon as possible.
