Gavin Hoey replaces JJ Garth, while Jack Tector is recalled in a 13-man Leinster Ligtning squad for the second T20 Festival in Bready.
Hoey, who has changed from pace bowling to leg-spin, keeps the Pembroke player quota at five, while there are four YMCA representatives.
The defending champions won their opening game, but suffered back-to-back defeats against the Knights and Warriors - the latter by one run in a thrilling contest.
“We’re excited about getting another opportunity so quickly,” says Jones. “Obviously when things don’t go as well as hoped, you’re always keen to get back to it.
“For Gavin, this is an exciting opportunity for him right now. We’ve been fortunate to work with him a lot over the last 12 months or so, as he has made the change to leg-spin.
"We’ve been really impressed throughout the training sessions and hubs last year alongside the contracted Ireland players. We believe he has a really strong skillset, suited to T20 cricket. His batting’s been impressive, and he moves well in the field too."
Leg-spin is in the Hoey genes with his father Conor winning 42 caps between 1991 and 95, taking 78 wickets including a best-bowling return of 6 for 19.

“Gavin brings an option with the ball that we feel we need, in terms of a wicket-taking ability, and we’re looking forward to giving him an opportunity, just as we did with Davey O’Halloran in the 50-over competition. It’s the only way we can learn about players sometimes and we’d rather be bold and aggressive with our approach, and I think this selection gives us that mindset going into the weekend.
Leinster Lightning face Munster Reds at 4pm on Friday, Northern Knights at 4pm on Saturday and the North West Warriors at 11am on Sunday.
