Hooper suffered a knee injury in Sunday's 34-20 loss to the Packers, Kelsey Conway of the Falcons' official site reports.
Hooper limped off the field on the Falcons' final drive of the game and was deemed questionable to return, but with the contest in the closing stages and already out of reach, he never retook the field. The 24-year-old caught four of six targets for 37 yards, as the Falcons offense struggled to score until the fourth quarter. The specifics of the injury remain unclear, but his status should receive some clarification by the time Atlanta resumes practice Wednesday.
