Adam Schefter and Chris Mortensen of ESPN first reported the news and noted Ngata intends to sign with Philly once free agency officially opens Wednesday.
However, it's not surprising the Lions chose not to aggressively pursue a reunion with Ngata.
The 34-year-old hasn't been quite the same player since arriving in Detroit, and he spent all but five games on injured reserve last season because of a bicep injury.
During his time in Detroit, Ngata managed six sacks and 53 total tackles.
Needless to say, that production was a far cry from what the Ravens were used to when Ngata racked up five Pro Bowl nods and two All-Pro selections during his nine-season stay in Baltimore.
That said, Ngata can still be a solid early-down gap-clogger who specializes in stuffing the run.
And if that's how the Eagles choose to deploy him, they could do worse—especially considering the limited short-term investment for the reigning Super Bowl champions.
