Williams was a first-round pick and was an All-Pro offensive tackle in his rookie season in 1994, but was suspended after testing positive for drugs. He never played in the NFL again, but the Eagles never released him, either - until yesterday.

The article goes on to note that Williams is now eligible to be claimed by any other NFL team.

I’m sure some statistician Redditors here could confirm/refute whether Williams is, technically, the longest-tenured player in Eagles history - and indeed in all of NFL history.
