Glovers boss Gary Johnson was disappointed with his side's display in their televised 2-0 defeat to Swindon on Tuesday night, a performance which deteriorated after the loss of their captain.
McAllister, who had been having painkilling injections in his ankle in recent matches, limped off four minutes after half-time but he had already picked up his 10th booking of the season which rules him out of Yeovil's next two matches.
"We had to give him a rest anyway, he had been having these injections and we knew we would have to give him a rest for the next couple of games and he has that anyway now with the 10th yellow card," Johnson said.
"We will have to deal without him which is a shame as without him we don't seem half the team."
One player who will now walk a disciplinary tightrope is Byron Webster who looks likely to feature despite being on nine yellow cards, one away from joining his captain in the stands.
