Pledger revealed in March that he had been diagnosed with colorectal cancer after months of feeling unwell and a string of inconclusive medical tests.
In an interview with the Herald in July, Pledger said five weeks of chemotherapy and radiation couldn't stop him from marrying long-time partner, Bailee Wilson, and returning to the court.
At the time Pledger was preparing for a low anterior resection to remove the tumour, while also undergoing a temporary ileostomy.
Pledger, who last played for the Tall Blacks in 2019, also won four Australian NBL titles with the New Zealand Breakers.
He played one game for the Southland Sharks in the New Zealand NBL this season, against the Canterbury Rams in June, contributing three points and three rebounds in a five-minute cameo.
