Pierce left Sunday's 33-30 loss to Kansas City in the first quarter after hurting his left heel and was ruled out. Indianapolis' team update said initial X-rays were negative, but the heel was the same one Pierce had surgically repaired in the spring. He had only just returned from the physically unable to perform list in August, and he managed five catches for 72 yards through two games before the setback.
The fantasy impact is more about role redistribution than a direct one-for-one replacement. NFL.com's report identified Josh Downs as the main remaining established Colts receiver, with Keenan Allen and Laquon Treadwell behind him. Indianapolis is also set to add former Giants receiver Darius Slayton, giving the team a player who can threaten downfield while the staff rebuilds the weekly target distribution. Managers should raise Downs' short-area opportunity and treat Slayton as a speculative add, with the caveat that the Colts have not yet published a complete post-injury depth chart.
