Palace twice took the lead through Academy forward Brandon Pierrick, but the hosts cancelled both out - with Tommy Woods poking home a goal-mouth scramble in the 91st minute to snatch a draw.
Mamadou Sakho stepped up his comeback with 60 minutes of action, whilst Connor Wickham played the full 90 in a youthful Palace side, managed by first team coach Dave Reddington.
