Warner is now into the third month of a one-year ban handed to him by Cricket Australia for his part in the Newlands ball-tampering scandal, but has started to make his way back into competitive cricket.
While Warner is banned from playing worldwide cricket for a year, he will be playing a lot of competitive cricket as he joined the Winnipeg Hawks for the inaugural edition of the Global T20 Canada, which starts on June 28.
Bancroft is still contracted to Western Australia and Perth Scorchers and is set to join them for pre-season training in June.
Short is no longer available for the tournament after being selected for Australia A's tour of India in August and September. He was the captain of Sunrisers Hyderabad team that won the IPL title in 2016.
However, Warner will now mark a return to the game when he turns out for the Winnipeg Hawks in the inaugural Global T20 tournament in Canada, ESPNcricinfo reported. He'll also be seen in the Darwin Strike League in July where he will play for Randwick Petersham, his Sydney-based boyhood club.
This will be Warner's first appearance in the Caribbean Premier League.
Stars general manager Mohammad Khan said: "We are excited to bring David to the Saint Lucia Stars". He further added his expectations of Warner adding value to the dressing room and on the field as well. Would it be the shot at redemption that would put his career back in the right path?
