Huge rookie mistake by Eagles' DeSean Jackson

Posted by ESPN.com's Matt Mosley
IRVING, Texas -- I'm not believing this: Eagles rookie DeSean Jackson catches a long pass for what would have been a touchdown, but decided to celebrate after 59 yards, short of the end zone. It was an unbelievable play. Eagles got the ball on the 1-yard line because the play was blown dead.

Jackson is now credited with a 60-yard catch. One play later, Brian Westbrook flipped into the end zone. Something tells me that Andy Reid will have a long talk with Jackson about that play. It was one of the most careless things I've ever seen. Cowboys fans couldn't have been too shocked, though. No one will ever forget the Leon Lett fumble.

At this rate, the first team to 50 points wins.
