Ross exited Thursday night's preseason game against the Patriots with a concussion and will not return, Dave Zangaro of NBC Sports Philadelphia reports.
Ross caught one of his two targets for nine yards prior to getting injured. It's the veteran wideout's lone catch of the preseason to date, and now he'll have to pass through the league's protocol if he's going to be cleared in time for the preseason finale versus Green Bay on Aug. 24.
