Dotson secured one of two targets for three yards in the Commanders' 13-6 preseason loss to the Dolphins on Saturday night.
Dotson was on the field with Terry McLaurin and Dyami Brown to open the game, playing ahead of Olamide Zaccheaus and rookie third-round pick Luke McCaffrey. Dotson is trying to hold on to the No. 2 receiver job while also taking a lot more slot snaps than he did last year.
