The Spitfires travel to Hove to take on Sussex Sharks with the race for a quarter-final spot heating up in the South Group.
Kent sit second in the table, three points adrift of leaders Somerset on 16 points after 11 matches with Glamorgan third and Gloucestershire fourth, each on 13 points.
Head coach Matt Walker said his side can take encouragement from the rain-affected home match against Sussex last month: “We batted brilliantly against them and started very positively, particularly against Rashid Khan.
“We’ve generally done well against all the high-quality spinners we’ve faced so far like Rashid and Mujeeb at Hampshire.
“The message is to play the ball not the man. We can’t be affected by the great players they have in their ranks and play with positivity.
“They are a dangerous side but there are so many in this group. The bowlers need to be religious with their disciplines as one or two sloppy overs can kill you in this format.
“We are one of four or five sides at the top and keep winning to secure a quarter-final.”
Australian duo Marcus Stoinis (hamstring) and Mitch Claydon (groin) are out so batsman Zak Crawley and paceman Grant Stewart could make their Kent T20 debuts.
