The NFL is looking into Dunta Robinson's hit on Jeremy Maclin in the third quarter of last night's game, a spokesman confirmed.
"It is under review like any play of that nature," spokesman Greg Aiello said in an email.
Aiello said he did not have a timetable for when a decision or announcement would be made. Typically, players receive a FedEx envelope from the league late in the week if they are to be fined.
Robinson hit Maclin with the crown of his helmet after Maclin made a 17-year reception. The play drew a 15-yard penalty.
Eagles coach Andy Reid declined to comment on the hit during his day-after news conference today, saying people who comment on those things usually get fined.
The hit will get added scrutiny because it happened on national television and also because Robinson was fined $25,000 (reduced from $50,000) for a hit last year that left DeSean Jackson with a concussion.
