CIYMS opener John Matchett has been added to the Knights' squads for their upcoming clashes with Leinster Lightning.

The Irish Under 19 international's strong early season form for both club and Emerging Knights is rewarded by a call-up to Simon Johnston's side for the first time.

Jacob Mulder is ruled out through injury while Greg Thompson misses the three-day match due to work commitments.
