Philadelphia Eagles star receiver A.J. Brown went down with an apparent knee injury in the first quarter of Sunday's 24-3 loss against the New York Giants.

Brown, the former Ole Miss star who played his first three seasons with the Tennessee Titans, caught a slant pass late in the first quarter and was tackled to the ground. He immediately began gripping his right knee with both hands.

Brown was initially ruled questionable to return by the Eagles before he was later ruled out of the game.
