Pep Guardiola conceded Ederson's injury "doesn't look good" as Manchester City were forced to wait on the severity of the issue.

Ederson had to be taken off at half-time during City's 2-0 win over Nottingham Forest on Sunday, a victory that took them back to within a point of Premier League leaders Arsenal with a game in hand.

The Brazil international needed treatment on an apparent shoulder injury after a collision with Forest defender Willy Boly.

Ederson was seen with his arm in a sling after full-time at the City Ground.

And Guardiola said: "It doesn't look good. We will see [on Monday] with the doctor." 

Stefan Ortega again stepped up in Ederson's absence, with City's number two having performed well when called upon this campaign.

Ortega has made seven Premier League appearances this season, making 16 saves from 22 shots on target faced, giving him a save percentage of 72.7.

Ederson, meanwhile, has a save percentage of 67.1, keeping out 53 of the 79 attempts on target he has faced.

Ortega has a slightly better goals prevented figure of 1.6 compared to Ederson's 1.0.
