Watch: Eagles interception sets up Saquon Barkley's third TD vs. Packers

The former undrafted free-agent Blankenship's fifth career interception set the Eagles up with excellent field position, and it wasn't long before the offense cashed in on the turnover.

On second-and-one from Green Bay's two-yard line, RB Saquon Barkley scored his third touchdown of his Eagles debut.

Barkley, who signed a three-year, $37.75M deal with Philadelphia this past offseason after spending the last six seasons with NFC East rival New York, previously scored on an 18-yard reception and 11-yard rush in the first half. It’s worth mentioning that the two-time Pro Bowler only scored three touchdowns in a single game once as a Giant. 

According to CBS Sports' Jeff Kerr, Barkley is just the second Eagles player to score a hat trick in their debut with the team, with the other being wideout Terrell Owens (2004). 

For what it's worth, Philadelphia advanced to Super Bowl XXXIX in Owens' first season with the team. Perhaps history will repeat itself once again in February.
