The former New Zealand captain was struck on the left forearm by South African paceman Wayne Parnell during his Trinbago Knight Riders' win over the Barbados Tridents, Australian media are reporting.
X-rays confirmed serious damage, ruling the 35-year-old out for the rest of the season for the competition leaders.
The Knight Riders finished the regular season with eight win from 10 games, ensuring they'll play in the first play-off game on Wednesday (NZT).
