DeSean Jackson's season is over

Injuries aren't the only reason for the Philadelphia Eagles' second straight flop of a season, but they sure have had a stunning number of them on the offensive side of the ball. The latest: Eagles coach Andy Reid announced at his Tuesday news conference that wide receiver DeSean Jackson has cracked ribs and would be placed on injured reserve, ending his 2012 season.

Jackson joins starting offensive linemen Jason Peters, Jason Kelce and Todd Herremans on injured reserve. Additionally, starting quarterback Michael Vick and running back LeSean McCoy remain sidelined as they continue to try to recover from concussions, and right guard Danny Watkins has been held out in recent weeks due in part to an ankle injury (though Watkins' absence from the starting lineup does also have a performance-related component). Add that up, and it's entirely possible the Eagles will play this Sunday night in Dallas with only four of their projected 2012 offensive starters.

Jackson leads the Eagles this year in catches (45) and receiving yards (700). The Eagles' downfield passing game has been a rumor for much of this season, but whatever looks Jackson had been getting are likely to be split up by wide receivers Jeremy Maclin, Riley Cooper and Jason Avant, whom Reid said could return from his own injury this week.

Monday night's loss to the Carolina Panthers was the Eagles' seventh in a row and dropped their record to 3-8 for the season. When Jackson reports next spring for the Eagles' offseason program, he's likely to be playing for a new head coach.
