Striker Les has an ankle injury and Gus is recovering from concussion, both sustained at West Ham last week, while wing-back 'Tano' is still troubled by an ankle knock he picked up against Arsenal.
Boss Glenn Hoddle reported no problems from Thursday's Worthington Cup victory at Fulham.
"We've got a few knocks and bruises but nothing that will affect us for Monday," he explained.
"The main objective over the next few days will be to see if Taricco, Ferdinand and Poyet can recover.
"Les took a nasty kick on the ankle at West Ham, right the way up his shin as well. Gus has a very badly bruised eye, very swollen but the good thing is that the neuro-surgeon has virtually given him the all clear.
"We'll see how it gets on when he has to head a few balls and we won't do that until Sunday, perhaps Monday morning."
Meanwhile, Tim Sherwood, Stephen Clemence and Steffen Iversen continue their march back to full fitness.
Glenn added: "Tim and Stevie Clemence have been long-termers, Tim's been stop-start all season, but they've played for the reserves and a behind-closed-doors friendly. Both need to get a bit of the rustiness out of the system."
That leaves Stephen Carr (knee), Gary Doherty (broken leg) and Chris Armstrong (groin) all on the recovery trail.
Les Ferdinand, Gus Poyet and Mauricio Taricco remain the doubts for Monday's Premiership clash against Bolton.
