The Potters have only picked up one win in the opening 10 games of the season and although they have played most of the top teams, last weekend's defeat at Norwich set the alarm bells ringing.
Stoke are desperate for a lift against a QPR side who are second from bottom but they will have to do it without Delap, who is due to undergo a hernia operation next week, while Owen is out with a hamstring injury that saw him miss last week's 1-0 defeat at Norwich.
Apart from that Tony Pulis has no fresh injury worries going into the clash and boss Tony Pulis is not planning big changes to his side despite the defeat at Carrow Road.
"I don't think there's much wrong," he said. "We have played really well and the stats are very encouraging apart from the final third. That's where we have got to be productive.
"We have probably played as well or better this year but we have to get results. Hopefully we will get some luck in front of goal because we're certainly creating chances. And we have to remember we've played six games away and only four at home."
