No they didn't. The Eagles sent Cooper to sensitivity training, drop us a line when you learn exactly how Jackson will be punished.
Again, he was fined an undisclosed amount by the Eagles and he is supposed to meet with local Jewish groups to discuss the Holocaust and why those words are especially hateful to Jews. That's the same thing as sensitivity training. But I get your point, we don't know if the fine is significant like Cooper's reportedly was or if he was just fine $500. I do not recall if Cooper was suspended but Jackson will not be suspended at this point.
Jeffery Laurie (the Eagles owner) has a history of giving people a second chance to atone for past bad behavior. Even though he's Jewish, that's a very Christian thing to do. But I will agree with those who say if DeSean Jackson says something as stupid and insensitive as this one more time again, he should be immediately cut.
