CJ de Villiers has replaced Marchant in the Titans squad after the 22-year-old fast bowler was diagnosed with a back injury that will keep him out of the tournament scheduled next month.
David Balcombe has replaced England T20 international Briggs in the Hampshire squad. Briggs is due to be married and go away on his honeymoon at the same time as Hampshire plays their second match in the CLT20 Qualifier -- against Sialkot Stallions on October 11 -- and would also be unavailable if England's domestic T20 champions progress to the Group Stage.
As a result, the CLT20 Technical Committee has approved Hampshire's application to replace Briggs for the duration of the tournament.
