U21s denied by last minute equaliser
A stoppage-time equaliser from Connor Dymand denied the Under-21s a seventh win in eight matches.
The visitors went ahead early on when Fisayo Adarabioyo slotted home, but a brace from Kenji Gorre saw the Swans lead at the interval.
A Kyle de Silva penalty levelled the scores ten minutes into the second half but Josh Sheehan's strike looked to have given the hosts all three points.
However, Palace had the final say when Dymand nodded home from a corner.
The result leaves the Under-21s in second place in Development League Two South following Cardiff City's win earlier in the day.
