Eagles WR Jackson out with concussion

Eagles coach Andy Reid said it will be a "real stretch" for receiver DeSean Jackson to play Sunday against Tennessee after suffering a concussion.

Jackson was injured in a nasty head-on collision with Atlanta cornerback Dunta Robinson. Jackson had soreness in his neck and shoulders on Monday. Typical for concussions, Reid said Jackson did not 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."

Jackson had scored both of Philadelphia's touchdowns and the Eagles led the Falcons 14-0 at the time of the collision. Philadelphia won 31-17.

Both players stayed on the turf for several minutes before being helped from the field. Jackson dropped a pass when hit by Robinson, who led with his head and hit Jackson in the helmet. Robinson was flagged for hitting a defenceless receiver.

"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."

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."

Jackson 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.

Reid also said Kolb will likely start at quarterback against the Titans. Michael Vick was the third QB vs. the Falcons and still hasn't fully recovered from injured rib cartilage that he sustained two weeks ago.

While Reid didn't totally rule out Vick, he said "there's a pretty good chance" Kolb will get his third straight start. Kolb hit 23 of 29 passes for 326 yards with three touchdowns and an interception vs. Atlanta.

The Eagles have a bye after the Titans, so resting Vick and Jackson would give the stars even more time to recover and possibly start Nov. 7 against Indianapolis.

Reid said Vick's health was improving, but he's still stiff around the ribs.
