Pulis was relieved to still be in the hat for the FA Cup fourth round.
"When the draw was made we know this would be a very tough fixture especially away from home," said Pulis.
"We have just come off the back of four very tough Premier League games. This is a tough ground to come to and they are a top Championship side.
"They played really well. They've got some dangerous players in their team and we are pleased with the result. They are a good side, Ian Holloway's got them well-motivated and it was always going to be difficult.
