In the backs, Rob Jewell replaces Matt Moore on the right wing and in the pack, Bruce Starr comes in for Jon Dawson, with Jason Leonard switching to tight head prop.

The bench will be confirmed on the morning of the game.

"There were a lot of very frustrated people in our changing room after the game at Newcastle last weekend," said NEC Harlequins Chief Executive Mark Evans. "This Saturday we face the Sharks, who are playing very well at the moment and come to us off a fine win away at London Irish last Sunday."

"However, our recent league record at the Stoop has been good and we are looking forward to playing in front of another packed house this weekend. Yes, we have to improve on our display from last Saturday, but I am sure that the players will be in the right frame of mind to put Newcastle behind them and give our supporters the performance they deserve."
