On a collision with Dunta Robinson of the Atlanta Falcons, Maclin at least escaped serious injury. Vick, twisting and turning on a play in the third quarter, knocked helmets with his Philadelphia Eagles teammate Todd Herremans and suffered a concussion that knocked him out of the Eagles’ 35-31 loss in Atlanta.

There was history behind the hit by Robinson, the kind of history that raises the question of whether he’s the dirtiest player in the league. A year ago, on a Sunday marked by several helmet-to-helmet collisions that prompted rules changes and fines, Robinson’s hit on DeSean Jackson gave Jackson a concussion. (He was fined $50,000 for that hit; it was reduced to $25,000.) There was some deja vu Sunday night.

“Unbelievable! Unbelievable that he has done it again,” Chris Collinsworth said on NBC’s “Sunday Night Football” broadcast.

“Now he's 2-for-2,” Maclin said of Robinson (via, who was fined for his hit on Jackson last year. “I was all right. It almost shocked me.”

Which means that the likely starter for the Eagles would be Kafka. With Vince Young inactive and recovering from a hamstring injury, Kafka stepped in and completed 7 of 9 passes for 72 yards.
