Manchester City midfielder James Milner will reportedly see a specialist on Monday to determine the extent of his toe injury.
The 26-year-old, who missed the 1-1 draw with Arsenal on Sunday, could reportedly be sidelined for a month with the issue.
Milner has made just two appearances for City thus far this season, but has been favoured by Roberto Mancini in the big matches.
City currently sit seventh in the Premier League table.
