Luka Doncic was looking to return on February 8 from a calf strain, according to Marc Stein of The Stein Line.
Doncic suffered the injury on Christmas and was originally scheduled to be re-evaluated after a month.
Conditioning concerns played a role in the Mavs looking to trade Doncic.
Doncic, who did not request a trade, was reportedly stunned by the deal.
