Manchester City midfielder Fernandinho will be scanned after suffering a knee injury in Wednesday's derby victory at Manchester United.
The Brazilian was substituted early in the second half of City's 2-0 win at Old Trafford after hurting himself blocking a shot from United's Paul Pogba.
The 33-year-old said: "We will see tomorrow. We are going to make the scan and we will see. I will talk to the doctor and he will make the best decision for everybody.
"When I blocked the shot from Paul I felt my knee. It twisted a little bit. I could continue playing but I came off. That's what it is."
City will hope the key midfielder will be able to prove his fitness for Sunday's Premier League trip to Burnley.
City returned to the top of the table, a point above Liverpool, as a result of their derby success and are now clear favourites to retain their crown. Both sides have three games remaining.
