Man City manager Pep Guardiola has provided a worrying update on the fitness of Fernandinho, who may not return from injury until the FA Cup final against Watford on May 18.
The Brazilian picked up a knee injury in City's 2-0 derby victory over Manchester United and was substituted even though he wanted to carry on.
It wasn't expected that the injury would be too serious and there was hope that he may have been available for the pivotal Premier League clash against Burnley on Sunday afternoon.
However, Fernandinho wasn't involved in the game and didn't travel to Turf Moor with the squad at all.
Prior to kick-off Guardiola offered a brief update on when the defensive midfielder could return.
"Really I don't know," the City boss told Sky Sports.

"I think maybe the last [game of the season] or maybe the [FA Cup] final, maybe. It'll take a little bit longer."
City face a tough task in Burnley who have improved considerably since the turn of the year and Guardiola was also full of praise for the day's opponents.
"It's a specific way of playing, they're so good playing the strikers and second balls, the crosses and attacking the box. it's not easy to play againts them ever. It gets more and more difficult in the last games, but we know what we have to do.
"All the teams in the Premier Laegue I think are taller than us! We have to defend second balls and impose our game."
