The only changes to the team from last week are on the bench. Former Wales captain Rob Howley returns from a slight back injury, while Mark Lock replaces the injured John Hart (also back).
"We have gone two games without conceding a try and have won the last three in a row," Gatland told the official Wasps website.
"It's important that we keep this winning momentum during November. Falcons are a strong side and will be looking to build on their win over Bath. We expect a battle and are well prepared."
