Brown (oblique) took part in Monday's OTA, Dave Zangaro of NBC Sports Philadelphia reports.
Brown joined the Eagles on a one-year deal in early May, and Monday is the first open session of practice in which he's participated. According to Daniel Gallen of The Harrisburg Patriot-News, the 29-year-old was working with the second-team nickel defense as he makes his return from the torn oblique that plagued him throughout the 2018 season.
