After a change in EFL rules, voted for by clubs, it means players loaned out on Standard and International Loans who have returned to their parent side are eligible for them again.
Previously players were registered with their loan club for the duration of the loan, whether six months or 12 months.
The new ruling takes effect if the player is coming back from a club whose division has been curtailed or has not qualified for the Play-Offs.
Bailey (Forest Green Rovers), Lakin (Stevenage) and Dacres-Cogley (Crawley Town) all had their League Two involvement ended when the regular season was called off on 9 June.
Availability is based on a limited number of other factors the parent club has to take into account as well.
But nonetheless it will be a boost for Head Coach Pep Clotet to have the three of them at his disposal.
Bailey made his big breakthrough this season and with Kerim Mrabti and Jacques Maghoma having departed will provide extra options across the attacking frontline.
Lakin's bite in midfield and a season of competitive action will stand him in good stead and of the trio, versatile defender Dacres-Cogley has the most experience.
