Cliftonville midfielders Aaron Harkin, Caoimhin McConnell and Ronan Wilson have been made available to other clubs.
Harkin, 27, joined the Reds from Institute in January 2019, pulling on the shirt on 15 occasions since then.
19-year-old McConnell spent last season on loan with Ards, making 23 Championship appearances and scoring twice while Wilson (21) clocked up 20 outings for the Reds during the most recent campaign.
Speaking to the official Cliftonville website, manager Paddy McLaughlin said: "One of the down sides of being a Manager is making players available to other clubs.
"At the same time, though, you have to be fair to the players themselves. All three of them have been excellent to work with and this is no fault of theirs, but we haven’t been able to give them the minutes they need out on the pitch and this is an opportunity for them to get game time and hopefully play regularly.
"I appreciate everything they’ve done here and wish them all the very best in whatever comes next in their careers."
