Michael McIndoe (MK Dons), Jermaine Grandison (Tranmere Rovers, pictured below) and Shaun Jeffers (Cheltenham Town) are all currently out on loan until January.
Speaking to the CT, Boothroyd said: "I`ve been keeping an eye on Michael, he`s had a hamstring injury and he`s been recovering but he played last Saturday so he`s back in the fold.
"And I think come January time with the likes of Michael, Jermaine and Shaun, decisions are going to have to be made on whether they go back out on loan.
"For me, I think the squad we`ve got in numbers is just right at the moment and I don`t want to disrupt that by bringing players back who need to play or bringing people back in who are just going to upset the numbers."
