Manchester City have been dealt a title blow with Ruben Dias facing up to six weeks out – starting with Sunday's derby against Manchester United.
Dias sustained a hamstring injury during Tuesday's FA Cup victory at Peterborough United and City's fears were confirmed after tests at the club's training base.
Pep Guardiola revealed that the 24-year-old, who makes up one-fifth of the team's leadership group, is set for at least a month on the sidelines.
That raises the prospect of Dias missing a crunch title showdown with Liverpool on April 10 and potentially both legs of a Champions League quarter-final.
