Palace led until the 96th minute, when a late equaliser against the run of play meant the points were shared.
"For the last majority of the game we nullified their press," Ward told Palace TV after full-time. "I think they only had maybe a handful of half-chances and opportunities. So obviously to concede so late on is bitterly disappointing.
"It's something that we need to learn from. I think we're moving in the right direction and I think that shows in the performances and the quality of the performances over the last few weeks. But it's obviously disappointing not to come away with all three points.
