Leicestershire Foxes are set to make changes for the Twenty20 Cup visit to Yorkshire Carnegie tonight.
Opener Hylton Ackerman, who has been struggling with a hamstring niggle, will be rested with the return to County Championship action on the horizon.
With Jeremy Snape now in retirement, senior coach Tim Boon has added Tom New and 17-year-old all-rounder Josh Cobb to the squad.
If both play, it would give the Foxes a youthful line-up with the likes of Sam Cliff, James Taylor and Jigar Naik also in contention, having all figured in the last few Twenty20 matches.
Leicestershire's latest 20-over outing brought a long-awaited - and much-needed - win over Nottinghamshire Outlaws on Tuesday evening, when Jim Allenby's steely nerve guided the Foxes to a five-run success.
Allenby had also featured in a productive partnership with skipper Paul Nixon which salvaged their side's innings after it had hit early trouble.
Now Boon is keen to see his players build on that victory, even if they are not in the running for the Twenty20 last-eight.
"There was a sense of relief on Tuesday," said Boon. "It was a great win in a game that chopped and changed.
"At 11-3 we had a good partnership between Paul and Jimmy, and that was really pleasing.
"The younger players created more energy in the field and that helped us to win the game.
"Facing the prospect of going through Twenty20 without winning a match, it was important that we moved forward.
"We practised hard again yesterday and the morale in the squad is very good."
All the pressure at Headingley will be on the home side, who need a win to retain their hopes of qualifying for the knock-out stages.
They edged the first meeting between the sides at Grace Road last week when Chris Taylor launched a last-ball six to complete a dramatic win.
Since then, Yorkshire have twice beaten Lancashire Lightning but they tied with Durham Dynamos and then lost to the same opposition, all of which has left them in fourth place in the north zone table with just two matches remaining.
The top two from each of the three regional groups qualify automatically for the quarter-finals, with the other two places going to the best third-placed sides.
A look at the make-up of the two squads, with Yorkshire boasting players of the quality and experience of Anthony McGrath, Jacques Rudolph, Matthew Hoggard and Darren Gough, suggests the home side should win with something to spare.
However, the Foxes' one-day record against Yorkshire in recent years has been a good one and, with little in the way of pressure on them, it will be fascinating to see how Leicestershire's young, re-jigged side measures up to the challenge.
