WORCESTER have told Harlequins -- the pressure's on you.

The Warriors travel to the Stoop on Saturday for a critical game in the race to avoid the Premiership drop.

And Sixways' head coach Andy Keast has turned up the heat on Mark Evans' misfiring men.

"The pressure is strongly on Harlequins," said Keast.

"I think what everybody looks at is the run-in, especially the home games, and it's the same for Harlequins. They will be focused on this game and the pressure is on them.

"For us, it's about accumulation of points and that's what we're travelling there for."

Worcester lie 10th in the Premiership table with Quins a place below because of fewer games won.

Both are two points ahead of bottom club Northampton and the weekend could be a pivotal one in the relegation battle with the Saints travelling to Wasps and another threatened club -- Leeds Tykes -- away at high-flying Sale tomorrow night.

Worcester recall Tim Collier, despite Phil Murphy impressing during the Warriors' 22-15 victory over Leeds in their last Premiership outing two weeks ago.

Collier has been the subject of speculation over the past few weeks with Biarritz, London Irish and Wasps all believed to be interested in the lock who is out of contract in the summer. He was also spotted by reporters at Harlequins' match with Natal Sharks last Thursday talking with Evans.

That has been dismissed by Keast and director of rugby John Brain who are both backing their man.

"We believe he wasn't there," said Brain. "However, we think it's totally irrelevant as far is Saturday is concerned.

"Whether he was there or not, it pales into total insignificance as far as the game is concerned because he's committed to Worcester and he will give, like he has all season, 100 per cent."

Ben Hinshelwood returns to the side following Six Nations duty with Scotland but there is no place in the starting 15 for Giscard Pieters with Daren O'Leary keeping hold of the jersey. Hooker Ben Daly returns to the 22 following three months out with a bicep injury.

Team: Delport; O'Leary, Rasmussen, Lombard, Hinshelwood; Brown, Powell; Windo, Van Niekerk, Horsman, Collier, Gillies, Hickey, Sanderson, MacLeod-Henderson. Replacements: Fortey, Daly, Murphy, Viali, Cole, Hayes, Pieters.
