Peterborough Town have four players in the Cambs squad for their must- win Unicorns Trophy tie against Norfolk at Leys School this Sunday.
Professional Paul McMahon skippers a side that could also include Lewis Bruce, Joe Dawborn and David Clarke.
Paceman Dawborn enjoyed a 3-0 spell in two overs on his way to figures of 4-39 for Leicestershire seconds in Durham this week.
Wisbech are represented by Josh Bowers and Sam Rippington, but James Williams misses out because of injury.
Ketton’s Rob Woolley and Michael Cafferkey will also play.
Cambs kept alive their hopes of qualification by beating Suffolk by six wickets at Bury St Edmunds last weekend.
Rippington (4-31) bowled superbly as Suffolk were shot out for just 83.
Cambs were 36-4 when Bruce was dismissed first ball, but Cafferkey (26no) and Woolley (22no) saw their side home without further alarm.
Cambs will qualify for the knockout stages if they beat Norfolk and Herts beat Suffolk.
