The two-time Pro Bowl wide receiver was inactive for the Philadelphia Eagles' 21-17 loss to Arizona on Sunday because he missed a team meeting.
"I thought it was the right thing to do," Eagles coach Andy Reid said. "I think it's out there now that he missed a meeting. He needs to step back and make sure that doesn't happen again."
A source familiar with the situation told ESPN NFL Insider Adam Schefter that Jackson's alarm didn't go off, causing the receiver to oversleep and miss the special teams meeting.
However, one person familiar with the situation told The Associated Press that it wasn't the first time Jackson has been late or missed a meeting, calling this the "final straw."
DeSean Jackson isn't helping his contract cause.
The two-time Pro Bowl wide receiver was inactive for the Philadelphia Eagles' 21-17 loss to Arizona on Sunday because he missed a team meeting.
"I'm not happy about it," Reid said.
Jackson's spokesman Bobby McRae told ESPN's Sal Paolantonio that the Eagles told Jackson to stay home.
"DeSean missed a meeting and he should be punished for that," McRae said. "But we think this punishment is totally unjustified. He should be there with his teammates. This is all part of an ongoing contract dispute with the Eagles."
