Reed's inability to play was not a surprise considering he was unable to practice all week and has now been diagnosed with at least five concussions since he started playing college football. Reed has been diagnosed with at least three concussions in the NFL, including one last season that caused him to miss two games. The Redskins lost both contests.
Reed's latest injury occurred in Sunday's win over the Baltimore Ravens, but he did not complain of any symptoms until Tuesday, when he entered the concussion protocol.
His loss is a big one for Washington's offense, even though it still has talented receivers in DeSean Jackson, Pierre Garcon and Jamison Crowder. The Redskins also have veteran tight end Vernon Davis, who has caught 10 passes this season. Niles Paul is their third tight end, though 15 of his 54 snaps this season have occurred at fullback. He has caught one pass. If the Redskins want to use a three-tight end look, they will use backup tackle Ty Nsekhe.
Reed has been quarterback Kirk Cousins' favorite target. In the last two years with Reed in the game, Cousins owns a 70.2 total quarterback rating out of 100, having thrown 32 touchdowns and 12 interceptions. Without Reed in the game, Cousins owns a 59.2 total QBR with 14 touchdowns and 13 interceptions.
This season, Reed has been targeted a team-high 45 times and leads the Redskins with 33 catches, 316 yards and two touchdowns. He's a primary target in the red zone as well. In the last two years, 12 of his 13 touchdown receptions have been inside the 20-yard line.
Cravens suffered a concussion in a Week 4 win over Cleveland. He did not play against Baltimore, but unlike Reed he was able to participate in practice, though he was limited. The rookie second-round pick has been a key part of Washington's sub packages. His absence likely will hurt more against Philadelphia than it did versus the Ravens because of how often the Eagles force teams out of their base defensive formations.
