What does it mean in bold?
35' FOUL! Milner shifts the ball from right to left and digs out a hanging cross towards the back stick, but the referee penalises Kane for slightly nudging Jaager in the back when trying to meet the cross.
This is football talk.
Shift is to move.
A cross is when a forward kicks the ball across the goal towards a striker.
A hanging cross is when the ball comes down in front of the goal as opposed to moving across it.
The back stick is one of the goalposts.
Kane tried to meet the ball that had been crossed, he tried to kick the ball, presumably towards goal.
Digging out suggests Milner managed to do it despite a shaky start, probably with a defender.
