Phil Jones' World Cup dreams may well have been wrecked by a shoulder injury he sustained in Manchester United's 3-1 win over Hull.
Jones clattered into Hull defender Maynor Figueroa while jumping for a corner in the 16th minute of the victory at Old Trafford, which came courtesy of a brace from debutant James Wilson and a strike from Robin van Persie.
Jones walked off the field and down the tunnel before being taken immediately to hospital.
England's World Cup squad is named on Monday, but United interim manager Ryan Giggs admits the defender could miss out.
"He has gone to hospital. We'll just have to assess it, but it didn't look great," Giggs said.
"Straight away he knew he had done something.
"He wanted to come straight off. Usually, as a player, you know it's something bad when you do that.
