KEEPER Jak Alnwick's stay with City has finished after just one game.

Alnwick returned to parent club Newcastle this week for treatment after damaging his wrist in training.

And today he revealed that he has to go under the knife, ruling him out for the rest of the season.

Alnwick tweeted: "Unfortunately my season is over. On route to Manchester to get wrist surgery."

Alnwick was only signed on loan by Phil Parkinson last month to replace Jordan Pickford, who was recalled by Sunderland.

His only City appearance was in the 1-1 draw at Notts County.

Untried Matt Urwin will continue on the bench as back-up to Ben Williams at Doncaster tonight.
