Brown was listed as a non-participant on Wednesday's practice report with an ankle injury.
Per Jamison Hensley of ESPN.com, the Ravens held a walk-through practice for their first session of the week after having just played a grueling overtime loss to the Raiders on Monday. What -- if anything -- Brown is able to do once the team retakes the field Thursday should provide added clarity with regard to his status for Sunday's game against Kansas City. The wideout logged 47 of 68 snaps on offense Week 1 and recorded six receptions for 69 yards and a touchdown.
