The 30-year old who was captaining Guyana Amazon Warriors and took his side to the fourth place right now at the points table.
Guptill and his wife Laura McGoldrick are expecting their first child next month.
“It’s unfortunate and hugely disappointing to lose Martin at this stage of the tournament but we empathize with his situation and he has our full support as he returns home to his family,” said Omar Khan, the operations manager of Warriors.
Guptill was on his fourth year with the warriors and has scored 142 runs this year on seven outings.
The retired wicket-keeper batsman Luke Ronchi has been called as a replacement for Martin who has just finished his time in England with the club Leicestershire.
“We welcome Luke to the Guyana Amazon Warriors family and his wealth of experience and explosive batting in this format will certainly be an asset to our team,” said the team operations manager.
Luke has quite good experience on this format and is looking to smash hard in this year’s CPL.
