Polk caught two of his three targets for six yards in Thursday's 14-13 preseason loss to the Eagles.
Polk had modest stats across 26 snaps, but he displayed some run-after-the-catch ability while shedding a pair of would-be tacklers on a six-yard completion from QB Drake Maye in the second quarter. The rookie second-round pick is a candidate to secure a key role, but whether that translates to initial fantasy relevance hinges on both his early-season workload and how heavily the team leans on the run amidst its transition at quarterback.
