Tom Soares put the Eagles ahead early in the second half, but Blackpool were level within ten minutes. And as the final whistle approached, Soares was shown a red card for apparently stamping on Andy Welsh.
Warnock refused to blame his player for the incident and instead focused on a decent performance.
"It was very unlucky, Tom couldn't get out of their player's way, but we won't be appealing," he said. "In fact, even with 10 men I thought we could have gone on and won it."
And the Eagles boss revealed he was excited to be back in football after a few months out of the game.
"I really enjoyed it and once we had taken the lead I thought we'd go on and win it," he added.
"My stomach was churning before the game, it's a nice challenge at a new club and the players didn't let me down."
