Football manager Paul Armstrong was confident Gaspar would take his place despite the relatively short layoff.
"He did everything that was required of him on Wednesday and we'll train again tomorrow, so if he gets through that he'll be right to play," he said.
"He knows his body better than anybody, so if he thinks he's right and the medical staff give him the okay then he'll play."
Richard Tambling and Brent Hartigan have also been added to the extended 25-man squad after strong showings with Coburg.
There have been no omissions from the side that fell to Port Adelaide by 13 points last week.
Carlton has added three players to its squad as it attempts to return to the winner's list for the first time since April.
Adam Bentick, Digby Morrell and Ian Prendergast have all earned recalls with their form in the VFL, but face anxious waits to see whether they will still be in the side after final selection on Friday.
As yet, no one has been omitted from the side that suffered a 24-point defeat at the hands of Hawthorn last week.
