Prior to the tackle, Jackson had scored twice for the Eagles as Philadelphia jumped out to a quick 14-0 lead on the Falcons, on their way to a 31-17 victory.
Then, quarterback Kevin Kolb tried to hit Jackson with a pass as he ran across the field.
Also Sunday, Steelers linebacker James Harrison knocked out both Josh Cribbs and Mohamed Massaquoi of the Browns on separate violent tackles in the the second quarter of Pittsburgh's 28-10 win over Cleveland.
As a result of those and other hits, the NFL is looking at further punishments, on top of fines. NFL vice president of football operations Ray Anderson told The Associated Press on Monday the league could start suspending players involved in dangerous helmet-to-helmet hits.
