The big striker limped off after just 36 minutes of the 1-0 defeat at the Walkers Stadium on Monday night.
With Dexter Blackstock already out long-term and David McGoldrick not yet fit, boss Billy Davies admits the loss of another forward could be damaging.
"He has an ankle problem so we will have to wait and see, but losing him and Dexter in successive weeks is not healthy because of the type of players they are," said Davies.
The Scott added: "We worked for two or three days on the way we wanted to play and once Dele went off we had to change that."
