PHILADELPHIA -- DeSean Jackson can't remember the vicious collision that left him with a concussion. That's a typical consequence for anyone who suffers such a violent head injury. So is missing playing time.
Jackson, the dynamic Eagles wide receiver, will almost certainly sit out Sunday's game against Tennessee after he was injured in a nasty head-on collision with Atlanta cornerback Dunta Robinson. Jackson had soreness in his neck and shoulders a day after the blast, but was otherwise in good spirits and receiving treatment Monday in the training room.
"I will tell you that it would be a stretch for him, a real stretch, for him to make it this weekend," coach Andy Reid said.
Jackson and Robinson were knocked out of Sunday's game after a frightening collision in which Robinson launched himself head first. Robinson also sustained a concussion.
Robinson was flagged for hitting a defenseless receiver. Both players stayed on the turf for several minutes before being helped from the field.
"He got a pretty good jolt, now," Reid said. "That was a big hit. I'm not sure I've seen one here quite like that one in our stadium. That was a big hit for both guys."
Not surprisingly, Jackson told Reid he didn't remember the hit that knocked him out.
"It's not like amnesia set in," Reid said. "He remembered his touchdowns and all the things that happened."
Before he was sidelined by the hit, Jackson was unstoppable. He gained 78 yards on three first-quarter touches, scoring on a 31-yard run and a 34-yard pass from Kevin Kolb. Then came the brutal hit that left him flat on the turf, motionless. Robinson was just as immobile.
"This was like a 'Rocky' movie," Reid said. "Very seldom do you see two guys collide and they're on the canvas there."
It's not the first time Jackson, who has 19 catches for 395 yards, was seriously flattened on the field.
He also suffered a concussion last season against Washington. He was injured then on a hit after running a short crossing pattern in the third quarter. He didn't lose consciousness and left the field on his own. He missed the next game, though.
"I think they're all different, and so you just have to go on the symptoms and see what happens, and listen to the doctors, and listen to the player and the trainer," he said.
