The NFL has been investigating tampering violations against the Falcons for their addition of Kirk Cousins and the Eagles for their Saquon Barkley signing. In the case of the latter, no discipline will be forthcoming. 
“After a thorough review of the Philadelphia Eagles signing of Saquon Barkley, the NFL today informed the club that the investigation did not discover sufficient evidence to support a finding that the Anti-Tampering Policy was violated,” a statement from the league reads (via NFL Network’s Tom Pelissero).
“In coming to this conclusion, the league reviewed phone logs, text messages and other documents related to Philadelphia’s free agency strategy and decision to sign Barkley. The NFL also interviewed several members of the organization, including [general manager] Howie Roseman and [head coach] Nick Sirianni, as well as Barkley and Penn State head coach James Franklin.”
Remarks made by Franklin indicated Roseman and Barkley directly spoke with one another before the opening of the new league year. For players who do not represent themselves – which is the case for Barkley – that is prohibited by league policy. Throughout the investigation, the Eagles have maintained no violation occurred.
That is the same for the Falcons, although Atlanta has been expected to receive a stiffer penalty than Philadelphia as a result of the Cousins inquiry. A recent report indicated both investigations would likely reach a conclusion soon, and that has proven to be the case.
The NFL’s statement notes that new evidence could prompt the Eagles investigation to be re-opened. As things stand now, however, no fines or loss of draft picks will be forthcoming for the team. Barkley is tied to Philadelphia through 2026 after he inked a $37.75MM pact in free agency.
