The England winger appeared to pull a muscle and had to be substituted in the 38th minute of the 5th round tie at Kenilworth Road. Grealish was visibly upset after going off and covered his face with his jacket. It was his first match back after <a href="https://www.goal.com/en-gb/lists/nightmare-for-jack-grealish-man-city-winger-limps-off-copenhagen-champions-league-groin-injury/blt187328e22cecb706" target="_blank">being forced off</a> early in City's Champions League clash with Copenhagen two weeks ago.

WHAT HAPPENED?

Grealish can't catch a break this season and has badly struggled to repeat his displays of the last campaign, when he was pivotal to City winning the treble. He missed a month at the start of the campaign with a knee injury and then had his house burgled in December. He has also being usurped in the team for most matches by Jeremy Doku.

Grealish was warned by Guardiola the day before the game at Luton that he <a href="https://www.goal.com/en-gb/lists/pep-guardiola-warns-jack-grealish-man-city-won-t-wait-rhythm-england-winger-performances-dipped-this-season/blt292ea2c3b41aceca#csee01bf70981cc03e" target="_blank">needed to make the most of the minutes</a> he got and had to return to form sharpish. The coach told reporters: "I cannot give three or four games for them to get their rhythm, they have to [find] the rhythm if playing 90 or 20 minutes. At a high level, the team doesn’t wait."

DID YOU KNOW?

Grealish looks certain to miss the Manchester derby against United on Sunday and will be a doubt for City's Champions League last-16 second leg against Copenhagen.
