The Colombia international was taken off as a precaution in the 3-3 draw at Manchester United after complaining of a tight calf and Ancelotti will not risk the forward if there is any doubt.
Pickford has sat out the last two matches with a rib injury and will also be assessed.

‘I have to wait until training to see if Pickford and James are available,’ said Ancelotti.
‘James had a little problem on his calf, a tight calf. I took him off after 70 minutes to avoid risk.
‘He will try (in training) and if he feels comfortable he is going to play; if not he will train Thursday, Friday and Saturday and if he is OK, he is going to play Sunday.’
Rodriguez, who scored against United last weekend, won’t be rushed back if he isn’t fully fit
