Brandon Brooks arrived at Lincoln Financial Field on Sunday morning before a 1 p.m. kickoff, according Doug Pederson.
"He was playing," the Eagles coach said on Monday. "He was there at the stadium ready to go when all this happened."
All this still doesn't have a specific name. The Eagles announced approximately 90 minutes before they were to face the Redskins that Brooks "began suffering an illness earlier today" and would be inactive.
Taken individually, a player missing a game on short notice during flu-cold season wouldn't be a big deal. But Brooks had been sidelined two games earlier with what was also described as a game-day illness, and the offensive lineman sat out two games - one in 2015 and another in 2014 - under similar circumstances with the Texans.
