Palace fans were expecting better after the shock home defeat by Nottingham Forest in midweek but a 7th minute goal from Leon Clarke had the home fans wondering what was going on.
Thankfully Watson saved Palace's blushes with a 2nd half spot kick after Shefki Kuqi was fouled.
Late on Wednesday hit the bar but it ended 1 - 1.
That's four games without a win now for Palace. Just 2 points from 12 have left the side 2 points above the relegation zone.
Next up is a trip to Coventry.
