Fans were given the chance to watch members of the first-team squad before players signed autographs at the side of the pitch.
Striker Ellis Simms was involved in the session and could make his first-team return this weekend after missing seven matches with a toe injury.
Our photographer Stuart Norton was at the stadium to capture some photos of the players in action.
Here are some of the images from the session:
